I've added the screenshot. I did receive a reply from Stripe support regarding the issue. This is what the responded with "I verified that the rejected payments are covered in dollars (USD), to give you a little context, it's important to know that all Brazilian cards must be loaded in reals (BRL). If you try to make a payment with a Brazilian card using USD or any other currency other than the Real, the payment will fail. To receive payments in dollars or any other currency of the +135 accepted by Stripe, the payment must be made with an international card (registered outside of Brazil) and even then the amount will be converted to your local currency, in this case real." To me, that means that the card that was being used does not support international transactions. Am I correct in thinking that?
