@evolab that's weird, when I click Forecast Model in my Windy Detail Widget settings it comes up with all the weather models available for the location I have selected (whether that's by my phones GPS or by favourite).
When I have HRRR selected, it shows HRRR data on the widget. When I click the widget it opens with HRRR as the selected model.
Maybe it's location specific? Maybe this is a bug for your location or something? Grasping at straws.
Hope you get it figured out.
I still agree though - we need to be able to customize and decide what model we want as a default.
