You cannot start the meeting 89032471426 because it is hosted by another user

Hi @vasanth,
Thank you for posting in the Developer Forum. Please see the responses to your inquires below:

You can resolve this intermittent issue by enabling Join before host option when scheduling meetings.

If you’re seeing this message, can you ensure that you have join_before_host enabled? To see the join before host option when scheduling meetings, you need to enable it in the web portal. If you do not select join before host, the participants will see a pop up dialog that says “The meeting is waiting for the host to join.”

You can enable authentication for users on your account and the user would want to sign-in with their licensed credentials. Please see our help documentation linked below for more details:

Please let me know if this helps.
