You're the first person to answer with T-Mobile. I wonder if they are still testing the app for their network. I know they have delayed apps from rolling out quickly before.Odd that Play Store still has the Oct 29 version (4.2.3), and no automatic update occurred. (Galaxy Note 20 Ultra 5G, tmo)
I recommend downloading the app from apkmirror, if you want to start using it now.
