My card was declined

Your question

I want to know why my perfect valid debit mastercard was declined.

Addon & CoApp version and details

I tried to purchase the license in order to use the product, but it tells me (repeatedly) that my card is declined. I don't understand. It is a perfectly fine card that I use every day and it has plenty of money on it.

Hi,
Sorry we do not manage payments, Stripe does.
