@kashoob I checked your payment attempts and I found the info about your card. There is a limit which was exceeded and that is the reason why this wasn't possible. Then the Fastspring started to block the card because of many attempts until June 22, 2023. So please check this limit on your end and try it that day again please. Also, there is no issue with Windy or Fastspring, and MasterCard.

@kashoob Hello, yes, the units for currents and tidal currents can be only changed on desktop.
