@Suty I don't know how to upload a screenshot here.
You should be able to download it by this link:
https://drive.google.com/file/d/1cPGQb3Aph9mUE4rQwpQzHV8PQ6lBX7pP/view?usp=drivesdk

You see the widget on the top in default size. Below the expanded one.

@Suty still not fixed?

@Suty Until the update one month ago a change of the widget size was never a problem.

@Suty are you able to replicate it?

@Suty I changed the size from 4x2 to 6x3

@Suty It's an issue with the widget size. I can replicate it.

@Suty Today I tried again to delete the widget and the app. After I installed the app and replaced the widget it was working. But when I changed the size and made it bigger to fit into my screen, the widget doesn't work anymore.
It seems like the problem only appears if you change the size of the widget to make it bigger.

I changed the size from 4x2 to 6x3

If I change the size back to 4x2 it is working again.

@dobrigoran yes, I did

@Suty after today's update I still have the same problem.

@Suty are you still working on it?

@Suty Sony Xperia 1 III
No App for battery management. Stamina mode is off.

@Suty After the update yesterday I still have the same issue.

@Suty Android 13, Windy 43.0.2

@Suty yes, I tried everything. It's still not working. After add a new widget it worked until the widget updated itself. Then not working anymore. It's empty. Even doesn't show the location.

@Suty I'm using the Detail Widget. The app has all permissions.

I've the problem since the last update of the windy app. There are no other changes.

The widget doesn't work anymore since the last update. It's empty. Doesn't show any information about failing.

You should make a Pro version of the App for the users who like to donate monthly.
Anyway, I'll donate monthly like I have to pay for other weather apps. But I would like to get a widget for 7 days weather forecast with the temperatures (min/max), weather icons, ... Just like other weather apps. Or a possibility to customize the widget you have now. I'm diver and the wind is not the only important thing I want to see in widget. Would be great!
