Why isn't my Apple Music working with Apple One Family Subscription?
Canceled Apple Music. Added apple one for family. Now my Apple Music won’t work

Correct. If you cancelled Apple Music, the version included with Apple One will not be available to you until the Apple One free trial is over and you are charged for the first time.

There was no need to cancel Apple Music directly. Apple One would have cancelled it automatically and provided a prorated refund for it.
