Hello, I am getting an error on some iOS users (if not all) when they try to make a purchase in my game.
They are charged by Apple, but the Playfab receipt validation fails with the following:
"TitleId": "AD88", "Source": "PlayFab", "Error": "InvalidEnvironmentForReceipt", "PaymentProvider": "iTunes Sandbox", "ReceiptContent": "[Actual Receipt]", "PaymentType": "ReceiptValidation", "Valid": false
I'm using Unity IAPs and didn't have a problem until recently on the Live build.
Any ideas on what is going wrong?
Thanks
