Unity IOS restore data in app store

The App store rejected my app for this reason





"Users restore transactions to maintain access to content they've already purchased. For example, when they upgrade to a new phone, they don't lose all of the items they purchased on the old phone. Include some mechanism in your app to let the user restore their purchases, such as a Restore Purchases button."





To restore previously purchased in-app purchase products, it would be appropriate to provide a "Restore" button and initiate the restore process when the "Restore" button is tapped by the user.









There is a way to track the user save data in the app store cloud?
there is a way to restore the transaction coins->object without an external server?

 

Apple requires a Restore button https://docs.unity3d.com/Manual/UnityIAPRestoringTransactions.html . This will fire a ProcessPurchase for each non-consumable/subscription product that was purchased previously.
