Another thing, on iOS, the developer does not know the identity of the person who pays for IAP. So it’s possible that someone can make a purchase, ask Apple for refund, and still keep the perks. Your receipt may show you have made IAP, but without screenshots, FM can’t link that purchase to your player account.
