It’s really slow on my older Chromebox converted to Ubuntu. Starting Firefox would take longer than 30 seconds to start when on snap vs native binary.

Google used to have Duo but I think they’ve got discontinued

It didn’t get discountinued it just got renamed to also Google meet. The web version duo.google.com still works.

Unfortunately Google hasn’t properly integrated the two apps, so you will need to download both versions of “Google Meet”
