Phone Swap RCS Issues

[DarkSorrow]

I did a phone swap from 1 Z Fold 7 to another and ever since the swap Google RCS messages don't work. It shows I'm connected to RCS but my messages fail to send and resend as texts. I've tried multiple things even resetting the phone, readding e Sim. I was on the phone with both Samsung and my carrier and they can't figure it out.
