Apple Music Family Sharing not recognizing shared subscription on iPhone

Hello, I would like to raise a complaint about Apple Music Family Sharing.

I have been added to an Apple Music Family subscription, and the family organiser can see that I should have access. I can also see that I am part of the Family Sharing group, but Apple Music on my iPhone continues to ask me to pay for a subscription.

I have checked my Family Sharing membership and tried troubleshooting, including signing out of and back into Media & Purchases, but the problem has not been resolved.

I should not have to pay separately for a subscription that is already being shared with me. Please investigate why my Apple Account is not recognising the family subscription, restore my access, and register my complaint.

Please provide a case reference number and explain what will be done to resolve this issue.
