The app sells non-consumable in-app purchases.
I also checked to enable family sharing.
However, there are frequent cases where users share purchases using the family sharing function and fail when attempting to purchase or restore from a device of the shared account.
Or, if a user who received the sharing makes a purchase, it will not be processed as shared payment information, but will be paid with the payment registered with the Apple ID of the current device.
I used StoreKit2 and use Transaction.currentEntitlements to get payment info after purchase or restore. However, non-consumable in-app purchase information that has been shared with the family does not arrive normally.
When I looked at the Storekit2 documentation, I know that there is nothing special handled or added in the API or code related to family sharing.
If I'm wrong on this part or if you know a good solution to this non-consumable payment - family sharing, please advise.
