Update 10/02/2020: The blocking feature provided by Safe Doc is deprecated. Please use the Google Meet’s built-in Host Controls > Let Everyone Share their screen = OFF option from the recent update of Google Meet in Sep 2020. However, the Host Control is on a session basis. If you prefer a permanent solution for all meetings, please try the following.

Google Meet is widely used in remote learning. One of problems is students can present their screens too and take over the control of presentation. This messed up the class.

This article explains how Safe Doc disable this screen sharing feature in Meet. If you have yet to install Safe Doc, apply 30 days trial.

What's changing

Before applying Safe Doc, the presentation feature appears in 2 places. One is in the "staging" page or "waiting room" and the other one is within in the meeting.

In the waiting room, there is a Present button next to the Join now button. Students are allowed to take over screen-sharing by default unless the teacher, as the meeting organizer, explicitly disallows participants presenting screens. Safe Doc removes the Present button permanently for all meetings.

On the bottom bar of the Google Meet after joining the meeting, the Present button is also removed as if the feature does not exist for students.
