About Family Sharing for in-app purchases, is there any place show "not shareable about some apps or some items in-app"? Thank you.

Hi arba_tw,

Thanks for details. If you have questions about a specific in-app purchase being shareable, reach out to directly to the app developer. You can see how to get started here: How to contact an app developer

Thanks.

Hi arba_tw

Thanks for using Apple Support Communities. We understand you have some questions about Family Sharing. We're happy to provide some information to help.

When it comes to sharing in-app purchases with Family Sharing, you can share subscriptions and in-app purchases from participating apps. You cannot share in-app purchases that are consumable (like coins or gems). You can see more about what you can and cannot share here: What types of content can I share with my family

Thanks.
