Gmail stopped sending notifications.

Please tell us some basic information before asking for help:
Model Name: asus zenfone 7 pro
Firmware Version: Android 10 (WW_29.13.47)
Rooted or not: not rooted
Frequency of Occurrence: yesterday night and today all morning
APP Name & APP Version (If your issue relates to the app): Gmail, latest version
========================================
Yesterday (after using the optimization tool to close unnecessary apps, maybe that was it), I completely stopped receiving Gmail notifications unless I open the app. Everything was working fiine before that. I already restarted the phone 3 times and messed with the setting to try and fix the lack of notifications; it still doesn´t work. My old 5z is working fine, so I am sure it´s on my 7 pro´s side, not on Gmail´s. If anyone has the same issue, please let me know how to fix it if you managed.

disable battery optimizations under Settings => Applications and notifications => Show all apps => Gmail => Battery and there set to Not optimize
go to Settings => Battery => Autorun manager and check if Gmail is allowed to autorun
got to Settings => Advanced => Mobile Manager => Memory Cleaner and check if you have "Turn on Super Clean mode" enabled, if so enter the app list and uncheck Gmail
