I can send a group message, if I'm the one that starts it, and receive one just fine. Issue I'm having is if someone else starts it or if I respond to a response in one I started I get another message with my response in it. I don't know how to stop this. I looked in settings to try and stop it but all I saw was to get something showing they person received it and something showing it was read. Both have been shutoff. Only seems to happen in a group message and I'm thinking it also does the same in a MMS. Any way to stop this so the same message stays and I don't have 3 or 4 messages for the same conversation?
EDIT: I was just able to find a post on Reddit having the same issue. Someone suggested doing a factory reset. Seems like it could be an issue for some that get a new SIM card on T-Mobile and I just came from Sprint so this could be the issue. I'd rather not do reset unless I have to. So does anyone know of another way to fix this?
