If you are struggling to get the video working from your computer this is easy to solve.
Perhaps you've seen a message like this:
Solution: Allow your camera
If you are using Chrome, find the camera icon on the top right of the url bar
This will enable you to reactivate your camera and microphone settings
Click the option labelled Ask if “yourschoolname” wants to access your camera and microphone
Choose the correct camera or your web camera.
Click Finished
Click the refresh page icon next to the page arrows on the top left of the web page
Please be patient while the page reloads... :)
Then when you're ready to re-enter your class with the new settings, please make sure you click Allow when prompted to start your camera.
You can also check the left corner of the URL bar and make sure the camera is enabled:
Now you should be all set. Enjoy your class!
