YogitaTalathi , via OnePlus 6T , Dec 25, 2021 : Hello There, It's been more than 2 months I am not receiving Gmail notifications and it's not syncing too. It's happening after the OS update. https://support.google.com/mail/tro...-settings,check-your-phone-or-tablet-settings I need to open gmail and refresh manually. I have tried everything possible from this thread and various other threads on the internet like changing settings, etc. Nothing seems to work for me. It is really frustrating. Please take a look into this asap. I have contacted Gmail team too. They are looking into it and they are suggesting that it is a device specific issue most probably. So, requesting OnePlus to intervene here and provide a solution. Thank you!
