I was about to start a new topic, when I saw this... I've having the same problems...
but here's the kicker, the webcam does work with video calls! yet when I try to show only my webcam, it will show my cam for a few seconds (only on my screen), and then it'll say "webcam session ended".
And so far, it only happens with one person... I can start my webcam with other people.
so is there some kind of setting on the profile that allows video calls, but disables webcam viewing?
EDIT: she logged into an older account, and the same thing happened... could this be a router issue? Firewall perhaps?
