JitsiMeetJS.events.conference.TRACK_ADDED failing for Firefox intermittently

I am using lib-jitsi-meet in our application, when I connect through my app using Firefox, I get joined into meeting(everyone gets USER_JOINED event) but sometimes Firefox participant don’t get TRACK_ADDED event, causing no remote tracks of other participants.

I have checked JICOFO logs, I can see “org.jitsi.protocol.xmpp.AbstractOperationSetJingle.sendAddSourceIQ().479 Notify add SSRC” log for Firefox participant, but still no event at client side.

Chrome doesn’t produce this issue.

Thanks in advance.

This is known issue with Firefox https://github.com/jitsi/jitsi-meet/issues/4461

Ok, thanks, I will keep track on those issues. #4461 and #4520.
