Nevertheless, after he revealed the Medium submit Monday, the corporate responded with a workaround reasonably than a real repair: “In gentle of this concern, we determined to provide our customers much more management of their video settings. As a part of our upcoming July 2019 launch, Zoom will apply and save the person’s video choice from their first Zoom assembly to all future Zoom conferences. Customers and system directors can nonetheless configure their shopper video settings to show OFF video when becoming a member of a gathering. This variation will apply to all shopper platforms.”
