Two Factor Authentication Cannot be Turn Off (Greyed out)
I need to turn off two factor authorization on my son's iphone (he's a family member on my icloud account). I've followed the instructions to disable and I get to the required screen. It clearly says the the Two Factor Authentication is "On", but there is no button/method to turn is "Off". It's literally greyed out (see below). How do I turn this off?
