Hey @aaronxu33,
Thank you for reaching out to the Zoom Developer Forum. Are you doing anything in the meeting prior to seeing this message or do you join a meeting and attempt to start the video and immediately see that message?
As a first step, I would try testing with the latest version of the Sample Web App (2.0.1) and follow our guide on Improving Web SDK Performance to make sure the browser is using the latest APIs.
Let me know if that helps.
Thanks,
Max
