1. Go to Settings > Family.
2. Tap your name.
3. Make a note of which Apple ID is listed.

4. Tap Purchases.
5. Tap Apple ID for Purchases and make sure that you're signed in with with the same Apple ID that you use for Family Sharing. If not, tap Share using secondary Apple ID and enter the Apple ID and password for that Apple ID.

Thanks!
