VoLTE is being constantly disabled - Moto G6 Plus Questions & Answers

I have the Brazilian retail (RETBR) variant of Moto G6 Plus, (XT1926-8) running Android 9.0 (PPWS29.116-16-15), and I'm having an issue where VoLTE is being randomly disabled, it is, the 4G icon disappears from the status bar. I can re-enable it by going to Phone info menu (by dialing *#*#4636#*#*) and toggling "VoLTE provisioning" on.
However, obviously I don't wanna do that every single time VoLTE is disabled, is there a way to have it enabled 100% of the time? Is this a firmware issue?

Restarts cause settings to change back to default?

Moto G5 (Amazon edition) on Verizon. Not rooted
I had configured some of the settings like adding battery % to top, network, etc.
However, when I turned off the device, and powered it back on, I lost most of my saved settings.
My network switched back to GSM so I couldn't make calls, but after some troubleshooting I realized that they switched me from CDMA. Adding the battery % on top took some figuring out but it went back to default of only the icon. Bluetooth turned off.
Is anyone else experiencing this settings bug during restarts?
I've owned at least 4 other Motorola phones but never seen this happen before.

Accessibility services turn off after restart

I've not noticed this before and not sure if it's a glitch in the Oreo beta, however everytime I restart my device (which has been a few times today with beta 2) my accessibility services are turned off, so BxActions stops working until I re-enable it in the settings, the same with Navbar apps.
Can anyone else confirm this?
Thanks,
YES! Same issue. However, I've had this issue dating back to my Galaxy Tab S on 6.0.1
I've just come to live with the fact that apps like Last Pass will never work properly unless I regularly (manually) provide them with accessibility access.

Wi-Fi stopped working please help

I think it started when I accidentally put the Wi-Fi setting panel/app into multi-window mode. I already had an app halfway at the top and even though it should filter apps that are not multi window capable, the wifi setting panel was available and tapped on it. It could not be placed at the bottom half though.
And/or I played with NFC tags and wrote my network onto a sticker then read it back.
Ever since, Wi-Fi is unavailable. The toggle just toggles the icon state, but no actual connection is made. When I swipe down from the status bar again, the Wi-Fi icon is enabled again. Second screen icon doesn't do anything. I can't get the list of available networks as it's frozen and empty. After a while it says "Wi-Fi isn't responding. Do you want to close it?" This seems to eat the CPU so much it drained the battery quickly. How to I reset this or bring back the normal behavior? Device is factory unlocked H990DS, 1 month old and not rooted.
Screenshots here
I tried:
Rebooting
Removing the battery and putting it back
Entering recovery with: adb reboot recovery (it didn't do anything just an icon with "no command")
Connecting via scanning my NFC sticker but it just freezes the connection prompt
Enabling hotspot (it doesn't turn on and cannot be configured, seems to use the same configuration app)

Enable ReconnectManager for FCM to Fix Delayed/Missing Notifications

I have tracked down the cause of my delayed/missing notifications to the FCM receiver not automatically re-connecting when I roam from one access point in my network to another with the same SSID. This behavior started after I did a factory reset and updated my 6T to OOS 10.3.2 from OOS 9.0.17 (whatever was the last version of Pie)
Does anyone know the setting to enable the Reconnect Manager for FCM? You can see the status by dialing *#*#426#*#* and turning on advanced view in the menu on the top right.
My notifications do not work when it is in a disconnected state. As soon as I turn WiFi off and back on the FCM service reconnects and I get all the notifications I was missing. I have waited over an hour and FCM never reconnects on its own.
I have searched on Google on how to enable this setting with no luck, I even tried the Heartbeat fixer apps for GCM but they do not enable the Reconnect Manager setting in FCM.
I have attached screenshots that show the logs and status of the FCM on my device.

TWRP Date/Time Problem

I am running TWRP v3.3.1-0 and I notice the date and time are way off. 2 years ago and several hours and many minutes behind the time. I made sure the time zone is set correct. I had it set for 24 hour time and changed it to 12 hour time, its still wrong. When I boot back to the system (LineageOS 15.1) the date/time is correct. Otherwise TWRP works as it should.
Any ideas ?
Problem related to Roaming Indicator Off
https://forum.xda-developers.com/g5-plus/help/roaming-indicator-off-t4088323
Thread title: Roaming Indicator Off
When I turn on Enhanced 4G LTE Mode (VoLTE), my carrier display is changed to “Roaming Indicator Off”.
My phone is XT1687 64GB/4GB + 128GB SD. LineageOS 15.1-20200414 (GothicIV, security patched Apr 5, 2020). My carrier is US Mobile as a virtual carrier of Verizon.
If I clear cache or remove SIM; reboot; reinsert, it displays US Mobile for a while – but then it goes back to “Roaming Indicator Off”. (Don’t do the #228# as it puts the phone in 3G only mode!!!)
From what I read this is a problem with the “Preferred Roaming List (PRL)”. This appears to be a carrier/provider problem – but I read it’s common in custom ROMs.
Any ideas to fix – besides turning off 4G?
=================================================================================================
When the phone shows the proper carrier; TWRP shows the correct date and time. When the phone is displaying "Roaming Indicator Off", the year shows 2018 in TWRP and the files it creates. In PERSIST , there is a "Time" directory, I was advised to erase them and reboot - and it had no effect.
If TWRP works fine then I'd wouldn't worry about the time and date honestly. Otherwise I believe you can set it manually.
