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?
