A host can start a few types of meetings:
The conditions to start each type of conference differ. An Instant meeting starts when the host and at least one participant join the room.
A scheduled meeting has three conditions to begin: at least one participant joins the room, the host is here and the scheduled time has come. Even if the host and a participant join at a later time, the scheduled event will still start.
A permanent room starts automatically once the host and a participant join. When both, host and participant, exit the Permanent Room, it restarts and will be ready to use again in seconds.
You'll be able to find all the future meetings in the Upcoming section. The ones you have finished will join the Past list. Click the Permanent section to see your permanent rooms.
