new Google Meet feature that those who utilize pop-up notifications will probably like. Now when you’re sharing your screen in a Google Meet call, Chrome will automatically mute and hide pop-up notifications from things like Gmail, Google Calendar, and Google Keep. It will also mute notifications from non-Google services like Slack and Intercom. It should be noted that notifications will re-appear when you stop sharing your screen.
I personally hate getting notifications on my desktop so having pop-ups appear while screen-sharing in Google Meet has never been an issue for me. However, I can see how having pop-ups appear while screen-sharing in Google Meet could represent a problem for teachers who do utilize pop-up notifications.
Like most new Google Meet features, this one is being rolled out over the course of the next few days.
