@Suty I used a web browser. I guess that means "Paddle".
Mixing two topics here - one is my failed attempt to pay with credit card. I would say ditch this topic, I will "try again later" (eh) or will open another thread about it.
The other topic is about Bitcoin payments. That's the OP. I understand that automatic renewal cannot work with Bitcoin. The one time payment can work just fine and would be an excellent addition to an already excellent Windy.
Thinking about it - automatic renewal is flawed also with credit cards, if we consider virtual one-time cards. A user can use a one-time card and get the lower price and choose automatic renewal and the renewal will never work after 1 year.
