Hello.

There's what seems to be an unusual occurrence happening with this module. ZC version 1.5.6c, Square version 1.5.

Customers are complaining they cannot checkout, that the credit card module is "stuck on displaying an error" whenever wrong data is entered.

We tested entering an invalid CC number and it displays an error message, as it should. We then entered a valid CC number, all data correctly, but the previous error message continues to display not letting us move forward with checkout. The only way to remove the error message is to go back to checkout_shipping, go back again to checkout_payment and re-enter all the payment info, or refresh the checkout_payment page, not ideal.

I'm assuming this could be solved by upgrading the Production API version on Square, but before I kill the store, I would like to ask which version of the Production API on Square I should upgrade to, based on the ZC/Square versions I currently have installed, and if I should also change my webhook endpoints to use this API version.

Thank you for the help!
