The Make an In-App Purchase Blueprint node supplies On Success / On Failure. These delegates return an enum of EInAppPurchaseState. One of the enum states is “Restored”. I believe this will allow the user to “re-purchase” but actually it just will allow you to re-run the save game code. Essentially you would just want to put a message saying “Purchase / Reactivate in app purchase by tapping on the product below” or something along those lines.
