I am currently mentoring a group of faculty during their "unscheduled introduction to the Canvas Community." One of the big challenges we've faced is doing their "traditional" classes online, but the Conferences tool is a fantastic resource.
However, today, one of them emailed me to say that "some outside outfit" had gatecrashed his Conference and forced him to abandon the session. I went in (with Teacher privileges) to investigate, but he had failed to record the session.
One of the reasons I prefer Conferences to Zoom or Webex is the lower likelihood of gatecrashers. I hope this is still the case, and that one of the students was being a jerk (and, if we can retrieve the logs, we can deal with that student severely).
