I just noticed that I no longer have an icon for the workspaces (activities button) in the Zorin taskbar (Zorin 18.1 Core)—regardless of the theme I have set.
It is set to "visible" in the taskbar settings, and I have disabled and re-enabled it several times, but that didn't help. Disabling the Zorin taskbar and reinstalling it also didn’t help, also not switching to other layouts and back in Zorin Appearance.
Is the activities button a GNOME extension? If so, what is it called?
Unfortunately, I don’t know what I might have changed so that it has disappeared .
What can I do to get it to show up again in the taskbar?
When I set the left super key to open activities, then the activities overview is shown, but the icon in the taskbar is not there.
