I'm having an issue with the widget as well, it shows the same temperature so the time and doesn't refresh, also some days are missing completely

When trying to refresh, nothing changes.
I've cleared cache, checked permissions, reinstalled the app. I've reinstalled the widget several times.
I'm running a pixel 6pro so it's stock Android, leads me to believe the issue is on your end. But please let me know if anything else can be done.
