Adding a person to family share to be able to use the Apple TV
I am trying to add one of our sons to our Family Share. His only Apple Device is an Apple TV. He has his own Apple ID. I have tried it twice to add him to the family share but I am not successful. He received the invite via email and when he clicked on it gave an error message that "there was a problem loading this page".
Apple TV 4K, tvOS 26
