I'm running Gnome metacity flashback on Ubuntu 22.04. After the upgrade, I had some issues: upgrade to 22.04 made Gnome metacity-flashback clock disappear
the problem is that "Appearance" is missing, and I can't get it back. I want to use dark mode, but cannot access it.
If I look at Gnome tweaks, changes to the appearance simply don't take effect.
How can I again get the "Appearance" tab back to the settings menu?
