You know how through Chrome menu > More tools > Add to taskbar... you can add websites to a Start menu entry, and then pin them to the Start screen, desktop, and taskbar?
The icons of most websites (except Toggl and Instagram) I add to Start just end up as a white capital letter with a colored background. Like this:
When I search for the application in Search though, they have a neat icon that's the same as the favicon. Also as in File Explorer (Open file location) and the taskbar. I've cleared my icon cache twice and nothing has changed.
What's the issue?
