connect app account and web account

[Matteo Facchini]

I subscribed to the premium version of the app, but I can't remember with which account, and I can't find the login page on the meteoblue app.
If there is no account on the app (?), I would like to connect my purchase to the web account that I created recently.
Furthermore (to add more confusion!), I logged in to windy with my apple account, to be able to post here...
