Jitsi stability vs Zoom - mobile and WiFi issues?

People,

I wanted members in my Extinction Rebellion group to use Jitsi instead of Zoom for security reasons and I got this reply:

and yes @philip_rhoades Jitsi is plagued with problems, doesn't work on some phones (including mine), which means if I'm not on a laptop, I'm not in the meeting

My experience so far has been that it is more a mobile and WiFi problem for Jitsi - everyone on wired connections seems to work fine? - but of course that may not be practical in all situations . .

PS I should add I am happy to help with any development or debugging I can do . .
