I have gnome-shell 3.36.7-0ubuntu0.20.04.1 installed from focal-proposed for three weeks now and my two-monitor setup is working great.
I also have the gnome-shell-extensions-gpaste (from Ubuntu universe) and the gsconnect extension (from https://extensions.gnome.org/extension/1319/gsconnect/) installed and running without any problems.
