I need to use WebEx in order to give evidence to a court in Scotland in a fortnight's time. I use Ubuntu 18.04. I have installed the WebEx app (debian distro) successfully and also a Firefox add-on from Cisco. I can connect OK, but I cannot connect to the court as a participant - only an attendee. With any browser (current Chromium, Firefox, Opera) then I always get the message:
Support Not Available
You can't start or join this Webex meeting because it's enabled for Webex Meetings video conferencing, which isn't supported by your browser, browser version, or operating system. Contact your administrator for more information.
Please can you help?
