I've been trough many post with solution and elsewhere on internet. Spent many hours to go trough every thing again and again on my phone. I'm getting desperate about that and there's no bridge close i can jump from...........
Just to be sure. I go in "information about email " ( my phone is in french... ), then hit "battery" and then there's this " back ground activity authorization " that i can't turn on. It's in light gray so there's a setting missing somewhere else to "high light" this option......
Yes, as said by Dem_Crumblies_TechYT please check Battery optimization settings.
If that doesn't work Re-add the Email Account. If there’s a configuration issue: Remove the account from the Email app. Add it back and re-enter your credentials.
