Hi all,All of a sudden the post request to my server for IAP receipt validation is breaking causing anyone who makes an IAP unable to download the IAP as the receipt validation request to my server fails to send. Removing the receipt from the post data seems to send the request fine.I am adding the receipt (with NSUTF8StringEncoding) to an NSDictionary and JSON encoding it before sending it off.If I add the receipt with base64EncodedStringWithOptions instead of UTF8 it sends off fine. This code has not been changed in 3 or 4 years so I'm not sure what's going on. Have apple changed the formatting of receipts all of a sudden or is it something else?Many thanks in advance.
