    Screen Sharing Trouble Shooting (myviewboard.com)

    In order to get screen sharing work, it should look like this.

    Also, please check on "Entity management" --> "Firewall whitelisting" page.

    If this still not work, could you please help asking which student device they were using to share screen?
    And also the teacher's instance ID for more investigation.

    Thank you,
