Push notifications not working while screen is off - Samsung Galaxy S8 Questions and Answers

I've recently switched over from iOS to a Samsung Galaxy S8 running Android 8. During the first week everything worked just fine. I was receiving push notifications on a regular basis. A few days ago suddenly notifications stopped working intermittently when screen is off. I couldn't find a pattern really. It does it both on Wi-Fi and 4G, for all apps. Sometimes push notifications work, sometimes they are delayed (receiving them after a few minutes) and sometimes they do not work at all.
Each time it doesn't work when I turn on the screen, all notifications pop up with both sound and visual.
What I checked so far:
- Notifications turned on for the specific apps and allowed on lockscreen
- Apps were also put into the "Unmonitored apps" under Device Maintenance - Battery
- Wi-Fi on during sleep set to always
- Data saver turned off
- Optimize battery usage - checked that the apps are set to off
- Even tried by enabling Always On Display setting - same behavior.
For me it seems that the something in the battery optimization process is messing up with the notification service. I can't say for sure if it happens for messages as well as I don't receive text messages so often, but it happens for all other apps: Gmail, Whatsapp and some other apps I use.
I noticed that under Optimize battery usage there are a lot of system services and they are all set to be optimized. Which I find very odd considering that probably some of them are very important for the system to run properly. Is it possible that there is a service there that handles notifications and I should switch off battery optimization for it as well? The only name I found close was a service called "notification" which I disabled, but without success. Still not getting push notifications.
Any idea what else can be checked? If I cannot find a solution to it I will most probably go back to iOS as this is very annoying. I heavily rely on notifications for work purposes as well.

Possible alamsolution running Check Notifications @ 0.05???

As we all know there is a major bug concerning the alarm in WM5. Very often i do net get a wake-up alarm at 07.00 in the morning
As far as i know. Every night at 0.00 WM runs a clean up program for notifications but i think there goes something wrong. When i manually run Check Notifications at 0.05 (delete all alarms set in start > settings > system > clock and alarms, run check notifications and then setting the alarmns back) my alarms run perfectly at 07.00 and 07.30 every time!
So i wonder if it is possible to write a program that does this automatically: delete any alarm entries in clockprogram, then run Check Notifications, and then set the alarms back as they were!??? Could this be possible to implement in a program? (By someone who is more a developer than myself)
Do a search for the "WRAP: Wizard Reliable Alarm Project" thread on here. I'm currently experimenting with turning the phone on at 23:59 and off again at 0:01 (automatically), giving it longer to do the standard calendar/alarm clean-up (as I suspect this could be the root of the problem) - this could suffer the same flaw as the alarms, however, with the device not completely waking up.
I am also experimenting with not putting the phone into standby (just turning off screen), but this has an erratic effect on battery power - it is, however, by far the most reliable way of making sure your alarm goes off. Remember, alarms are more reliable if you keep the phone on charge overnight - a temporary solution until we fix it is to use something like MortSaver to turn the screen off at night, and your alarm will sound.

Issues with apps connecting to network?

I've noticed this so far with Gmail, Facebook and News Republic
Intermittently Facebook will show a 'can't connect right now' message which won't correct unless I switch off my data connection and start again. The exact same occurs with News Republic which is a news feed app. With Gmail it's a little different - it goes through phases of not push updating and instead me having to go into the app to refresh and find 10 new emails
I've gone to settings and made sure none of them are set to stop notifications for battery optimisation, and made sure they all have access to background data. I do tend to switch between normal and power saving mode with a tendency to power saving mode and I wonder whether it's related to that? Anyone else noticing similar issues?
Also noticing the same, running systemless xposed + root, a few xposed addons which I've disabled ones I felt could potentially be causing the issue.
Still no luck, it's annoying.

Problem with push notifications when phone is sleeping / idle

Hello!
I'm running a stock Verizon HTC 10 with the latest OTA updates. This phone seems to have a problem with push notifications after it has been "sleeping" or idle for awhile. I don't know exactly what that time period is, but it seems to be about 30 minutes. Once the screen goes black and the phone has been idle in this state for this time period, the phone stops getting (or checking for-however that works) push notifications. There is no blinking LED or sound notification that mail has come for gmail or Outlook. The phone will still answer calls and notify upon receipt of text messages. Usually within a few seconds of turning the screen on from the idle state, the gmail and Outlook notifications come. When the phone screen is on, or within a few minutes of turning the screen off, the push notifications will still come, but then stop.
I googled about this, and there seems to be quite a bit of discussion about it. I have tried the suggested remedies, but they don't work (unsync/sync gmail, clear data/cache for the apps, turn battery optimization off, delete/re-add accounts, along with some others). For work, I have a Samsung Galaxy S7, and it doesn't have this problem. Furthermore, my wife also has an HTC 10, and her phone doesn't seem to have the problem either (although I have not tested it thoroughly).
I've been through various settings, checked the do not disturb settings, but I can't seem to figure this out. I am probably missing some setting. It seems that the phone is going into some deep sleep mode after a period of time and disabling these apps, but keeping others, like the phone and SMS functions, alive.
Any suggestions?
Thanks!

Are you using power saver mode? What about the boost+ app?
Also a lot of people started having similar issues after the first update to Nougat for U.S Unlocked. Later updates fixed the issue, but it sometimes still happening with Gmail for me.

I am not using power saver mode, and the Verizon version doesn't have the boost+ app installed.

Android 9.0 - delayed notifications

Hello,
recently I decided to update my Mi A1 to Android 9.0. Unfortunately it turns out that I have a big problem with notifications. Sometimes they come "normally", at the time they should. However, it often happens that notifications appear with a delay of 10-30 minutes. Sometimes they don't even come at all until I turn on the screen. In this case of course I am talking about the lack of notifications when the phone is unused. However, I once had a case when notifications from Facebook Messenger did not come for more than 3 hours, despite the use of the phone - car navigation, browsing the Internet, notes, etc. Messenger didn't show notifications of new messages until I opened it. I've tried to turn off the adaptive battery mode, but it did not help. Does anyone know how to solve this problem? Everything worked well on Android 8.0, but I do not feel like going back to it again.

I will try this, hope it helps. However on Android 8.0 I had optimization turned on and notifications were working fine.

No incoming texts over night until morning; they never show up

Hi folks,
I've got the 6013 model in the US, running on AT&T, completely stock never rooted, fully updated to 10.3.11. Either the most recent update, or the one before that, seems to have caused an issue where texts sent to me overnight or in early morning before I first use the phone never show up. I've missed some important notifications due to this. The worst thing is they NEVER show up... they aren't just delayed until I wake the phone up. After I start using the phone, new texts make it through just fine. The phone seems to be sleeping deeper or something and not getting any of these cellular-based texts. Emails and other notifications based on wifi internet seem to be showing up fine.
Do not disturb is NOT enabled (and, I've tried toggling it on and off without change). This has been going on for weeks or longer, multiple reboots, etc.. I've checked my default texting app (Textra) and the phone's built-in Messages app... the texts aren't in either app. They just never show up.
What else can I look into to check the cause of this and hopefully a fix?
Thanks!
As a test today, I sent a text from my work phone to my personal OnePlus when I got up (late! Father's Day!) before interacting with my OnePlus at all. It did receive the text just fine. I think the cellular radio may be on some timer and going to sleep / waking up on some sort of schedule. Where are the settings for controlling this kind of thing? I haven't messed with this phone's settings much... it just worked fine out of the box and ever since for the last two and a half years until recent update messed this text thing up.
Further information: In Settings, Battery, Battery Saver is OFF (I've never enabled this) and under battery optimization I noticed Textra was set for Intelligent Control; I've toggled this to Don't Optimize. "Messages" was not present; I never use it.
Is there anything else to try? Note that the phone is plugged in and fully charged at the time these issues are occurring.

Dude, not sure but hope it will work,
anyway trying will cost nothing...
Go to settings > battery > battery optimization >
hit on upper right 3 dots and select advanced optimization,
then be sure " SLEEP STANDBY OPTIMIZATION"
is toggled OFF.
Try again and cross your finger...
Cheers

Thanks @Dadditz , that was already off. Sigh. Not sure why this happens. I've tested when I get up at 7 am, sending a text from another phone, and my 6T receives it, but during the darker hours of the night, no joy. Thanks for the reply, though.
Just as a follow up, the problem seems intermittent. I got some 4 am texts from my sump alarm when the wifi went down briefly. No idea what's going on, but it's intermittent rather than constant.
