Re-submitting card details that have been declined, without re-entering them produces a server error:
{"errors": [@"code": "CARD_TOKEN_USED","detail": "Card nonce already used with a different idempotency key; please request new nonce.","category": "INVALID_REQUEST_ERROR"]}
Either create a new nonce when re-submitting, or remove the facility to re-submit card details that have been declined - i.e. force the user to re-enter the card details or use a different card.
