In sandbox envirnoment, after making an auto-renewing subscription, all calls to: https://sandbox.itunes.apple.com/verifyReceipt Always returns:{ environment = Sandbox; status = 21004;}This error is meant to mean that the password sent with the request in wrong.I am sending both the "receipt-data", and the "password". And I have checked a million times that the "password" matches the shared secret in iTunes Connect.This same call works fine when validating a receipt before an anto-renewing subscription has been purchased.So I am just wondering if this is a current issue on Apple's end, and if anyone else is experiencing the same problem?
