I'm a merchant, and trying to use some of the funds owed me to buy a product. I go to check out, click the "pay with in store credit button" and it still apparently insists on having a credit card? I get this error: ERROR You have not entered a valid credit card expiration date. Please go back and try again. Since I've used the in store credit for purchase before without having to give it a CC (which I don't have anyway) I know it used to work. Please let me know when that's fixed. Thanks!
