Have just bought a new iPad (iOS 10.3.1) for my son - our first and only Apple device. Since he's only 10, have been trying to set up Family Sharing with little success.
Once logged in under his profile, he can click Ask to Buy, however on returning to my profile there is no sign of the request. A friend has suggested that there ought to be an 'approve in person' option, but one does not appear.
I don't know whether it's related, or coincidental, however: 1) content restrictions set up on his profile are applied to my profile when I log in 2) there is no ability to add apps to a wishlist (just Twitter, Facebook, Mail etc) on either of our profiles when in the App Store
