I am unable to use a Vitade HD826 connected via USB to a MacBook Pro OS Catalina 10.15.6 with Zoom, WebEx and GoToMeeting. All these apps have permission to use the camera in System Preferences Security and Privacy. But turning on this USB camera for the software mentioned only produces a black window screen. The camera works fine with FaceTime and PhotoBooth on the MacBook and works well on my iMac Catalina 10.15.6 with FaceTime, PhotoBooth AND Zoom (Have not tried WebEX or GoToMeeting). I have tried Apple Support without any luck and even reset the NVRAM/PRAM. What's the issue?
