Hello @petra-pik ,
I'm running version 26.1.10 but it's still not working properly.
However the behaviour has changed:
Instead of showing the wrong location in the morning, now an error message like "location could not be detected" shows in the widget. Even if the location in the evening before was absolutely correct and the phone wasn't touched all night. Entering settings and hitting the update button fixes this issue for the next few hours.
Android still doesn't offer the option to grant windy location access any time.
This was working for so long just perfect and now the widget produces so many problems ?!
