Why can't I share my purchases across Family Sharing?
posted on 2017/08/17
The Family Sharing feature on iOS allows you to share apps, but not their in-app purchases, with family members' accounts. This means that what you purchase within an app can only be used on the account that made the purchase. It cannot transfer over.
