Hey @alexbudin , thanks for bringing this up. This is expected behavior for Zoom Meetings and the Meeting SDK (Web, mobile, and desktop platforms). If a meeting is occurring and the host leaves, a host is assigned until an authenticated host rejoins the meeting.
Following the thread in 2020 about 1.8.x, we did introduce a change to re-join/reclaim the meeting host permission using the host signature in the join process of the Web Meeting SDK.
If you assign Co-host or alternate host to a participant, they will receive host permission rather than another participant.
Additionally, in the event that a meeting host ends their session and has not ended the meeting, you can update meeting status using the REST API to update meeting status.
