You can now easily turn your microphone and camera ON or OFF even when viewing your video in Picture-in-Picture (PIP) mode.
(*The controls are only available for your own video. The buttons will not appear when another person's video is displayed.)
'Maximize' your video window from the top of the full screen. Then, click the 'PIP button' (Picture-in-Picture button).
You will see the video window and control buttons appear at the bottom right of your screen.
Now you can easily switch your microphone and camera ON/OFF while working in other tabs!
