How can I subscribe to Apple Music family subscription?
I am trying to sign up for an Apple Music Family subscription. I clicked the link: https://music.apple.com/deeplink?app=music&p=subscribe-family&at=1000l4QJ&ct=kbj_family&itscg=10000&itsct=kbj_fam
I accepted the 1 month free trial. My fingerprint allowed the subscription to proceed. I got the message
"You Have Already Authorised Five Computers
You can still make purchases on this computer, but you will need to transfer them to an authorized machine or device to play them. If you wish to play purchases on this computer, you will need to first deauthorise a currently authorised computer."
Leaving aside the issue of this absurd 5-computer limit, what's going on here?
I've never subscribed to Apple Music before, I have 2 Mac computers and no other Apple devices. Apple's obtuse support docs say to open Account > Authorizations on Apple Music, which doesn't help since I haven't signed in (due to lack of subscription) so literally nothing has been "authorized". I don't subscribe to any Apple services except iCloud+ so there's no TV subscription either.
Can somebody please assist me?
