@Suty Thanks for the reply. I'd go with the second option. Cheers.

Hi,
Please help me.
When registering on Windy.com, I entered my email address with a typo, then changed it, but the purchase was probably made using the old WRONG address.

My premium subscription has been activated and is working, but I cannot manage it on Windy.com!

So I can't access paddle.net because it requires an email address that doesn't exist.
