Fold 6 on T-Mobile keep getting downgraded from 5G UC to Standard 5G

[Zrnie]

I'm still waiting for OneUI 7 for the Fold6 but until then I'm not sure why I keep getting downgraded from 5G UC to Standard 5G (in my upper right-hand corner)

It isn't because of my plan, because swapping out SIMs from a Flip5 that has 5G UC support doesn't make sense. I'm wondering if anyone else has this issue. I'm going to try again with T-Mobile support but I highly doubt they will assume it isn't them and not me. Even though a S21U & S23U in my house has "UC" access

Any ideas?

It would definitely be t-mobile issue of course they will deny that or have you do troubleshooting which of course will do nothing
