Why can’t I modify my apple id ?

Nothing at all!? You were able to check a couple of the threads, and walk through the step given, all in two minutes?! Incredible!

Did you try to turn of screen time as suggested in this thread?

Did you see the reply in this thread? A forced restart, as suggested, takes all of two minutes, not counting the time it takes to check out the rest of the suggestions given.

If I am misunderstanding something, and non of the replies in the threads are of assistance, then please Contact Apple Support.

BTW, your welcome!
