If the Join before host option is enabled, the first person who joins a meeting will automatically be made the host and will have full control over the meeting.
See the Host and Co-Host Controls in a Meeting page of the Zoom Help Center for a video tutorial and information about the host controls for each device. As the host, you can control various aspects of the meeting, such as managing the participants. When you schedule a Zoom meeting, you are considered the host of that meeting.
See the Scheduling Meetings page of the Zoom Help Center for a video tutorial and information about the meeting options for each device.
When you schedule a recurring meeting, each occurrence uses the same meeting ID and settings. You can use Zoom to schedule a one-time meeting or a recurring meeting.
