Hi, I am going to be re-configuring my wife's phone to set it up on a Family Sharing account. That will involve changing the Itunes ID currently being used on her phone. A few questions: 1. If the ID is changed, do you have to delete and reinstall all existing apps in order to not have to input the old password? 2. If yes, to No. 1 there anyway to easily reset/restore the phone to remove all existing apps so they can be re-downloaded with the new apple id? I thought about doing a Reset and setting it up as a new phone but wouldnt i then lose all of her other settings? Thanks.
