Hello,we started receiving a lot of 21002 status codes when validate receipts using https://buy.itunes.apple.com/verifyReceiptThis looks like some signature problem because succesfully validated receipts have signature length 1669 and Apple Worldwide Developer Relations Certification AuthorityAt the same time, receipts that didn't pass validation have signature length 988 and Apple iTunes Store Certification Authority.And most of them sent from iOS <= 9.3.3Has anybody faced such a problem?
