Cannot sign in to Apple TV app purchased by family member/sharing
My son purchased/subscribes to CBS All Access via family sharing. When I try to sign in on Apple TV (or my iPhone) using his credentials, I receive the message that the user name + password do not match. However, when I sign in to iCloud using the same credentials, there is no problem. That particular app is a monthly subscription and is current. Any ideas?????
Apple TV 4K, tvOS 12
