Hi  RyanWoolsquare did you find the issue ? I am facing same symptoms

for me I get 21002 when the receipt is malformed I removed the == example : "receipt-data": "MIIV .... *** .... XmhV7MUVTm4OrNM64xhNLtug1qRc6ScSTNiKo3r7gI3AUGuq4b4MW53Wc6PR6C0abpt104SiY4dFEDzgG8gWXU5VseFd0zOmbI5BgawyIrA8EuBozxwMJlzcN9hXyTIjqsJR3NbOFFEeEb/vyWXTOwQaXiC==" returned : { "sucсess": true, "message": "", "data": { "status": 21002 } } but removing same equal : "receipt-data": "MIIV .... *** .... XmhV7MUVTm4OrNM64xhNLtug1qRc6ScSTNiKo3r7gI3AUGuq4b4MW53Wc6PR6C0abpt104SiY4dFEDzgG8gWXU5VseFd0zOmbI5BgawyIrA8EuBozxwMJlzcN9hXyTIjqsJR3NbOFFEeEb/vyWXTOwQaXiC" got this result : { "sucсess": true, "message": "", "data": { "environment": "Production", "receipt": { "receipt_type": "Production", "adam_id": 156XXXXX90, "app_item_id": 15XXXXX0, .... "product_id": "hygea__.XXXX _ership", "original_transaction_id": "XXXXXXX", "auto_renew_status": "1" } ], "status": 0 } }
