having the exact same fucking problem. with no clear reason at all, my mastercard debit card was declined. idk why.
Could you try again? Please use the same email and credit card you previously tried
it's debit, not credit, maybe that's a problem?
i tried using paypal without making an account, it said (roughly translated) : "the issuer of the card denies this purchase, please try using a different card". do i really have to make a PayPal account rn? how long does it take?
