Hey @jackson.sod,

Thank you for providing that video, that definitely helped to demonstrate the issue. Please send an email to developersupport@zoom.us with a link to this thread.

In that email, please include a meeting ID where you saw this as well as the email/participant ID of a user that joined via mobile and exhibited this issue.

I’ll use that information to investigate this further.
