I'm adding IAP and I need to validate the local receipt before listing the options that are available on the store, but for some reason the receipt validation is failing, or is not found, even after an SKReceiptRefreshRequest is made. This is working in Testflight without a problem but the review team isn't able to get past this step.
Any ideas on what might be different in a production receipt and a sandbox receipt (other than the originalApplicationVersion)?
