Information
When participants join a meeting, place them in a waiting room and require the host to admit them individually. Enabling the waiting room automatically disables the setting for allowing participants to join before host.
Rationale:
This option ensures that the participants are by default entered into meeting.
Impact:
When hundreds of participants are joining, the Co-Hosts has to admit all participants and may take time.
Solution
Go into the Zoom Admin Dashboard on the zoom website. Account Management -> Account Settings -> Meeting -> Waiting Room and ensure it is set to enabled.
