I have made three or four sessions now with jitsi with approx. 10 people. We have run into issues with screen sharing of different kinds:
When the first attendee shared the screen and stops sharing, a second user struggles and is unable to do the same. The sharing bottom is greyed out and nobody from the meeting can share again. Even after logging out the meeting and re-join it doesnt work.
When sharing the screen, in some browser like Chrome you can select to transfer audio as well. This is a nice option to share e.g. a Youtube music video with the others. But for Firefox this doesnt work and there is nothing to hook at and this option is out of range.
What can we do?
