So, this is new, but several days ago my bubble notification stopped working with Facebook Messenger. I tried several different things, from re-downloading the app, restarting the phone to playing with the notification bat in settings, but still no change. Can someone give me advice, because the bubbles are the only way to see the notification.
Make sure you check to see that your messenger app is up-to date to its latest version, also as a similar notification you can go to Settings -> Notifications -> Advanced Settings -> Floating notifications -> and select Bubbles. The notification "Bubbles" is not quite the same as Messenger's native bubbles that appear but should work as a work-around until Facebook can fix the issue.
