I've been using Manjaro for a few months and it's been great so far. I'm using GNOME and the Materia GTK theme for my desktop.
However, while the Materia Light Theme works perfectly, I can't switch to the Materia Dark Theme for some reason. This is what happens when I try to change the theme:
System Info: Gnome 3.36.6, X11 display manager and 64-bit architecture
Is there some terminal command I can use to switch the theme? What should I do? Any help will be greatly appreciated.
