Hi,
Apple Dev Support never got back to us. Hence, as a workaround, we simply created a new in-app purchase which is identical to the broken IAP except it has a new product identifier of course. The app still handles the old IAP in the receipt (for users who bought it in the past) but when the user taps the purchase button the app purchases the new IAP.
