New phone

This just happened to me when activating my new iPhone..I got stuck in a loop needing to enter Apple ID password then verify my passcode then enter “other phone” previous passcode over and over but the phone kept not being able to verify even tho I was entering passcode correctly (as the same passcode is what was actively unlocking my device while this was happening). I FINALLY figured it out. I had a bunch of apps that needed UPDATED (within App Store) at the time of transfer from previous phone to new phone. Once I updated all of those individual apps, i was able to successfully sign in with my Apple ID password and stay signed in AND verify my passcode. That finally broke the loop without having to reset phone or sign out of iCloud etc as all of those steps did not work to resolve the issue (even tho that’s what every forum post I reviewed said to do to resolve it. It didn’t work for me but updating all those apps did work immediately).
