Plugin version 0.3.6 fixes the loading issues caused by changes to windy. Sorry it took this long.
This is now the 5th time in 4 years I had to update the plugin because some change to windy broke it. If this trend continues, I can't guarantee that I'd be willing/able to do this in the future - especially if the info about the breaking changes comes from users complaining that it doesn't work anymore; some less polite than others. Unless things change, this is no longer an ecosystem I want to spend time contributing to.
So if someone else wants to take over the maintenance of this plugin - or rewrite it - they are more than welcome to do so; otherwise this might be the last update. Thanks for the support until now though!
