I have been having issues with RCS working on my phone since I've gotten it. The issue rears its head mostly in group chats where I do not receive about 2/3 of messages sent to me. This has resulted in me being inadvertently excluded from social events because people didn't know I wasn't receiving messages and obviously I didn't know either. I have had to disable RCS to reliably receive messages from my friends. I am also no longer part of a friend group chat and have to rely on my wife to convey information to me about social outings.

Feels like using T-Mobile makes me a second-class citizen. Perhaps T-Mobile wants us to change carriers?

Your issue is a Samsung issue. Google messages and Samsung devices been having issue. Doesn't matter the carrier and which RCS server around the world.

We had no issues with our Galaxy S21+ on Verizon, only when we moved to T-Mobile and got new S23+. You can even see T-Mobile is using their own servers for RCS when you view the RCS settings about info.
