Apple Music, Family Sharing
I pay for the family sharing for apple music and invited my step dad to join, When he tries to download music for offline use, he receives the message "You must transfer this device to your Apple ID to play content saved offline. You will be unable to transfer this device again for 90 days." he then gets an option to transfer or cancel. When he selects transfer nothing happens. His device is linked to the current Apple ID and isn’t connected to any other devices, any suggestions?
