Required DLIFE app update now won’t allow access

IPhone 12 digital life app mandatory app update. Logging in is fine and using facial recognition 2nd attempt gets checkmark so it’s OK, but I get circular login requests. I briefly see the AT&T logo but returns to user ID. Sometimes after 6-10 login attempts I can view the camera & data but then I’m logged out & can’t log back in. Now, after circling back more than 15 times I need tech support.
