Hi, similar issue here. I purchased Windy Premium on the Apple Store on my iPhone. It works great in the iphone app and iPhone browser (Chrome).

When I go to windy.com on my desktop Chrome browser, it sees I'm logged in with the same account, but prompts me to upgrade to Premium to get 1-hour forecasts.

I've followed the steps in this article as best I can, except it never prompts me to restore my purchase on the iPhone, because it already sees that I have Premium.

When I try to restore the purchase on my desktop, it asks for a FastSpring code, which I don't have since I purchased it in the AppStore.

I've logged out of Windy on the desktop and logged back in, with no improvement.

How can I get the premium access (on the desktop) that I paid for (in the App Store)?

Thanks,
