T-Mobile RCS Messaging Stability Issues

Are you still having this issue? I got a new T-Mobile s23 ultra 3 weeks ago and RCS has been terrible. So unreliable. There's no rhyme or reason to when it will/won't decide to work. I did all the T-Mobile troubleshooting and all the Google troubleshooting and even did a factory reset a few days ago. I have been on every forum with other users who have had the same issue. I called T-Mobile today and told them what troubleshooting I did, they transferred me to Samsung advanced support, and it still isn't working right. I wish I would have returned it within the 14 days and got an unlocked version instead. Lesson learned, I guess.
