I have a Samsung Galaxy S8 and I have always used google messages. I am on Tmobile in the US and have all available updates (android 9). recently I noticed i can send a message to someone and the reply comes back as a new group, with their name and my name. Then if I try and reply it will not work. It looks like it works but the messages are never sent. I can go back to the group without my name and send messages just fine. I have the RCS enabled since it was allowed. Any ideas what is causing this?
