I just replaced one self designed icon with an updated version. While the BasicUI is picking up that one immediately, I fail get a refresh in MainUI. It sticks to the old icon version.
I even created a new item as test, but selecting the category, reps. the icon returns the old icon.
Changing a widget, shows the old icon.
Thus, where is the MainUI storing the icon information of sleep designed icons, and how to get it refreshed?
