Finally fixed the problem.
1. Go to "Settings"
2. Go to "Apps & Notifications"
3. Select "Messenger"
4. Select "Notifications"
5. Click on...
I've tried I believe every possible option that came to my mind regarding settings and it still doesn't work. It started with my 3T and same issue...
I noticed that when I am turned on "Vibrate" mode the phone does not vibrate as well
Am I the only one not getting notification/message sound for Messenger on OnePlus 7 Pro?
Hi my 3T screen is flashing and the phone is very slow. Any ideas what's wrong?
