What if a co-host joined before the person who is designated to host the meeting?
The Host can transfer the host role by opening the Participant Panel, finding the name of the person who should become host, and hover the cursor over the name until a blue button labeled “More ...” shows up. Click the More button and select Make Host. Hosts can take back Host Privileges at any time. You can get to the Participant Panel by clicking on the button on the bottom of the app.
