Unable to change theme using terminal but can do via Tweaks

I did

gsettings set org.gnome.desktop.wm.preferences theme Adwaita

but nothing happens, except that when I do

gsettings get org.gnome.desktop.wm.preferences theme

I do get Adwaita (But the theme doesn't change).

But in GNOME Tweaks I am able to change it manually.

I would like to do it via terminal so that I can change it with Cron. Any suggestions on what I did wrong?

That key is no longer used in GNOME, window decorations are now dictated by the GTK+ theme.

To check the current theme, run

gsettings get org.gnome.desktop.interface gtk-theme

You can use set to load your preferred theme.
