Failure to Update Apple Payment

It is rumored that Apple requires you use a payment method from the same country to which your ID is also set. However, Apple's own support article specifically helping you with declined payment methods: If your payment method is declined in the App Store or iTunes Store - Apple Support says: "You might need to ask your financial institution to allow international purchases on your debit or credit card". If Apple is requiring you to use a card from the same country it certainly isn't including a simple statement to that effect in any of its documentation that I have found. If anything, its own documentation is implying international use is possible. Nevertheless, saying you must use a card from the same country is frequently officially recommended by Apple staff as a solution in similar posts I have seen regarding international payment methods (I presume this is applicable in your case since you specifically draw attentio to international payment methods).
