Apple Music and Family Sharing

[ciarals]

Hello. In this weekend I’ve set up all my family iOS devices under the Family Sharing option. It’s configured in this way:

• My Apple ID (the master one) registered to my iPhone, my Apple Watch, my iPad Pro, OUR Apple TV, OUR Mac.
• My wife’s Apple ID registered to her iPhone, OUR Apple TV, OUR Mac
• My son’s Apple ID registered to his iPad

I previously had an Apple Musc yearly subscription and yesterday I changed it to Family Subscription so also my wife can use it on her iPhone (and it works great, of course).

Everything seemed to work great, only the Mac was missing the final configuration. On the Mac me and my wife have 2 different user accounts, each one connected with its Apple ID, so iCloud sync, iCloud Photos, etc are all working greath for both of us in our respective accounts.

Only Apple Music for my wife was missing. I opened my iTunes to check that everything was fine and all was fine. I switched Mac account, opened her iTunes (for the first time), tried to activate Apple Music on her iTunes (Preferences, iCloud Music Library) and then the bloody 90 days error came out.

So, how can I solve this? How can me and my wife use our Apple Music accounts on our 2 different user accounts on the same Mac?

Thank you!
