Auto dark/light mode

i thought gnome 43 had an auto dark/light mode but i cannot find it, wondering where is it if it’s present

or maybe it’s the defaulf mode on theme switcher and just don’t work?(at least for me)

It can do automatic color temperature adjustment, called Nightlight

I am not aware of auto switchting to dark mode forth and back.

You can try “Night Theme Switcher” extension

i was already using that, but removed it cause thought gnome 43 had it by default…
