(1)Cannot zoom in the screen whenever needed. Like when the host turn the camera on, you'll see the video in a small square screen, just like you are using a Smartphone but the size of the video frame is as small as a feature phone's screen and you can't even zoom in. (2) Whenever I rotate the phone in landscape, a lot of shared content is cropped. (3) It displays the host's name right on the bottom part of the shared video which hides whatever comes behind it. ETC.
