What should I do if the camera or microphone icon shows with a exclamation mark?

There are two possibilities.

• The device cannot be recognized. The device may be damaged. Please change the device and restart Cloud Whiteboard and try again.
• The browser does not have permission to use the camera or microphone. Please follow the instructions to enable the camera and microphone permissions in the browser.(Please go to the settings of your browser, check and allow the use of the microphone and camera on the privacy and website permissions related pages)
