Screentime code and phone reset
Put screentime on phone to limit activity, but forgot password. Tried everything possible. Didn't work. Screentime limits things it shouldn't limit, so without a screentime password, the suggestion by the apple customer support person was to factory reset the phone. Backed everything up and then finally tried to reset it, but it asked for the screentime password before the factory reset could take place, so we're out of luck.
