I have used Jitsi in my Macbook Pro with no problems. I recently got a new MacBook Air and find I am unable to share screen. I get “screen sharing failed. Something went wrong with your screen sharing extension permissions. Please reload and try again”. My screen sharing preferences are fine (as far as I can tell). I am able to share my screen in Zoom.
Zoom is an app, you need to give same permissions to your browser in system preferences.
Thank you. I have given access to Chrome and Zoom. Since I use jitsi in Chrome I think it should be OK.
