Mog Station does not support changing credit/debit card if card type hasn't changed.
Let me illustrate the problem with an example.
- Customer has a MasterCard
- Customer is issued a new MasterCard from bank.
- Customer goes to enter new MasterCard number in MogStation through the Add/Change Subscriptions process.
- Because their new card the same type as their old type (MasterCard) they have no reason to change the payment method from MasterCard to something else.
- User is told "No changes have been made to your subscription or payment method."
Well, yes, because it's STILL a Master Card, but the card/number itself is different. This is an overzealous validation and it prevents me from updating my payment method.
