I haven't been getting any notifications from Facebook, Messenger, doorbell app, Youtube, sports apps for a few days.
The only thing I seem to get is phone calls and texts.
I've changed every setting I can possibly think of, Focus mode is not on, notifications are allowed, I've gone so far as to reset all settings, I've done recovery mode and reinstalled the most recent software update; 27.0.1.
I don't know what else to do.
