Host Sharing Enhancements-
As March 26th, the screen sharing settings within your account have automatically defaulted to “Only Host”. This setting gives hosts sole permission to share content within their meetings by default.
How do I give meeting participants the ability to share?
If you’d like to give participants screen sharing permission when hosting your next meeting, simply click the arrow to the right of the Screen Sharing icon, select Advanced Sharing Options and select All Participants.
