Family Sharing Of App Store Purchases
If you’re unfamiliar with it from other apps, here are some helpful steps to use Family Sharing for Movie Maker 3D Plus:
The person who is the Organizer of the Family Sharing should launch the iOS, iPadOS or macOS Settings app and open the Family section to make sure that Purchase Sharing is enabled.
The person who is the Organizer should launch the Movie Maker 3D app and purchase a Movie Maker 3D Plus subscription by tapping on the Movie Maker 3D Plus banner.
To check that a subscription purchase will be shared with other family members, the person who is the Organizer can launch the iOS App Store app, tap the Account button (upper right corner circular face button), then Subscriptions, then the Movie Maker 3D Plus subscription. Then verify that Share with Family is enabled and enable it if it is not.
Other members of the family can launch the Movie Maker 3D app on their own devices, tap the Add (+) button, tap a section like “Furniture", then tap the Restore Purchases button.
That will automatically download the shared family subscription. It can sometimes take a few seconds to a minute.
When Restore has completed successfully, the buttons on the Add view will change to indicate that the purchases are now available to the other family member and the Subscribe button will change to Subscribed.
