T-Mobile RCS Messaging Stability Issues

After updating my Galaxy S22 Ultra (T-Mobile variant) from One UI 5 to One UI 6, I am no longer able to send RCS text messages via the Google Messages app; SMS and MMS works fine. And yes, RCS is enabled in the Google Messages settings.

 

I've tried clearing the app and cache data for Google Messages, Carrier Services, Google Play Store, and Google Play Services. I've uninstalled and reinstalled Google Messages and Carrier Services (both production and beta versions). And I've even wiped the cache partition.

 

Lastly, I factory reset my phone and even with a fresh install of the OS, the issue persists.

 

Since I didn't experience this issue prior to updating to One UI 6, I have concluded that this is an issue with One UI 6.

 

Is anyone else experiencing this issue? 

This happened to us when we moved to T-Mobile in Dec and got new S23+ phones. Nothing fixes it because T-Mobile is using their own servers in the Google messages RCS process, instead of using the established Google Jibe server. They said they're fixing that but apparently instead of only affecting new phones they're switching everyone to their servers worth updates, thus breaking more and more people. We finally gave up and went straight SMS because we were missing so many messages.
