Dear all, we are using the Stripe integration to pay for our products. However, we have one product which is free of charge. If the user selects this product, he shouldn't get charged. It is possible of course to not show the whole payment input with a conditional logic. So the user selects the free product and doesn't see at all the payment flow. However, it seems to be not possible to click to submitting button then. This button always requires some input in the credit card field, even if this field isn't shown and even if the product is free of charge. Did anybody encounter the same problem and does anybody know how to solve it?
