Hello @vooxo, this is not a bug.
Default layer is wind and it will show up every time you open Windy. On desktop you can solve this by bookmarking favorite layer.
Anyway we appreciate your feedback and will take it into account when preparing future improvements.

Have a great day!

@Cysiek
It’s not possible to get another layer at starting the App.
On website, you can start from the URL of your preferred layer e.g. from temp layer URL

Good idea.
