>Chime also allows a meeting to start before (or even without) the host attending. How often have you had a meeting scheduled by senior leader, then they get pulled away and everyone is stuck in the virtual waiting room and end up coordinating/meeting in Slack instead? With Chime, the meeting starts anyway and the host can join when (if) they become available.

Not sure about other videoconferencing services but I never had this issue with zoom.
