I tried to add a Saudi Bank Debit card and it automatically stores it in the app but before I did this it always rejects it and it never stores it. When I activate this card last month it always says that "card is not supported" but today when I tried to activate it again the message "card is not supported" no longer appears but it just says "error", "try again later". I firmly believe we're getting really close to have this service be activated very soon.
