Having the same issue. Want to leave beta program but it's telling me it's not available because I switched service providers even though I did not.
Hi! I updated my Carrier from AT&T Prepaid to AT&T Wireless (PostPaid) but I'm still using an unlocked S21 and I'm getting this error. Is it possible to update my registration as well. Or is it possible to at least withdraw me from the beta program if it's not possible.
