Sorry if this is a stupid question, but is the Edge shortcut supposed to be added to the Applications -> Internet menu on installation? I'm running Ubunut Mate 20.04 (Mate 1.24.0). Installed by downloading the .deb file and running with GDebiPackageManager.
I was able to add to the task bar with a custom app launcher that calls microsoft-edge-dev. Otherwise I must launch it from terminal.
So far I like it and am looking forward to being able to sync profile.
