I have joined my Zoom call, and I am the host, but I am unable to manage participants or use other features.

If you have joined by adding the meeting ID (the number at the end of the link) into the Zoom desktop client or the browser version of Zoom, you'll not have this issue. Also, if you're teaching a zoom class via Canvas, you need to click start on the Zoom tab for the meeting you wish to host/join.

Please contact us either by emailing: help@iq.harvard.edu or calling our Help desk # (617) 495-4734 and we will contact the HUIT Zoom Admin to fix this issue for you on the server-side, and then after the meeting can figure out what might have caused this issue.
