Just updated manjaro gnome today, gnome 3.34.1. Indicator displays and populates as expected, but any attempt to launch an application in the menu (Evolution and Pidgin in my case) results in no action. journalctl -f reveals "Usage of object.actor is deprecated for MessageMenu_MessageMenu" in environment.js.
It is becoming more and more clear to me why so many gnome shell extensions get abandoned: Every gnome shell update breaks so many of them.
