ID Password
It is for months now, as from getting my 11 that sporadically I have to re-sign in again.. Message "update Apple ID - upon entering message "verification failed - unknow error occurred.
Going through the whole security questions issue only to get the same reaction.
I do it daily and the all of a sudden it takes the password and work for a couple of days only to do it again.
I have restarted, update and whatever but problem keep on coming back.
iPhone 11, iOS 14
