My daughter accepted my invite to shared family plan and I added her to my Apple Music subscription but it’s not working

Hi Drein15,

We see you're posting from the Set up Family Sharing resource. If you got that all configured correctly you'll want to make sure that you've got the right Apple Music subscription setup. Here's how you can do that: Get an Apple Music family subscription - Apple Support

If you've already got an Apple Music family subscription, you can use the steps here to ensure that it's being shared with the group: Share Apple and App Store subscriptions with family members on iPhone - Apple Support

If things persist we'd recommend reaching out for support here: Get Support

Take care.
