OK. That sucks. I cancelled the old account, but I am certainly not paying one year twice. I guess Windy has just lost a customer... you should change this!
Best regards!

@korina thanks for the answer, but what if I cannot restore it on my old device? It doesn‘t work anymore ...

Hi there!
I just purchased the yearly premium subscription 3 weeks ago but changed my phone from android to iOS. Do I now have to cancel the subscription and pay again? It seems there is no way to restore the purchase ...
