The only way I've found to get the widget to update is to tap it, open the app and then exit. I had updated Geir previously in a separate inquiry he had sent, but in testing the update - which takes 24 hours - we found additional update issues.
Everyone seems to have gone crazy for the new look Samsung is pushing out with Samsung Experience, the successor to Touch Wiz.
As a result, there have been quite a few applications ported over from the Galaxy S8 to older Samsung phones.
On the Samsung Galaxy S6 a weather widget is placed on the home screen, which originates from the App provider Accu Weather.
With this widget, you can easily adjust the weather and time of your home, so you have this always present on the home screen.
You now have the weather widget again placed on your Samsung Galaxy S6 homescreen and thus have an overview of the current weather at a preset location.
