U1601128850115 , via OnePlus Nord Gray Onyx , Sep 22, 2021 : Does anyone of you experience Gmail app not syncing? Mine stop syncing last 20th of December 2020. Up until now, it doesn't sync anymore. I don't receive mail notifications also as of today. My app is up to date. Do you know any Fix from this? I tried to force stop the app and clear all data and cache but to no avail.
