I can receive and send texts. But I don’t get a notification when I receive one. Despite my setting being show all notification. It used to be fine until I done a phone update. Now my phone says messenger not working.
I was having the same problem till I reset my phone (right now), now I get notifications, but I’m still having the problem of multiple threads generating with the same contact # …..very annoying. Try resetting the phone, hopefully that helps!
Go into your text settings my mother in law was having this problem and it was because the text notifications were off. If you have any wuestions let me know
