Known issues with presenter mode in meet.jit.si?

Hi Team Jitsi,

Presenter mode was announced in December last year. The announcement said to unmute your video when sharing your screen to enter presenter mode.

However, I can not unmute my video while sharing my screen. Otherwise, screen sharing, audio and video works as expected. Jitsi Meet shows a preview of my webcam when I click to show the webcam menu. Below the preview of the C270 there is a link saying Preview unavailable.

My webcam is a Logitech C270. Below the preview of the C270 there is a link saying Preview unavailable.

Any help with this issue is greatly appreciated.

Cheers,
Arne
