Why can't I see video?

There are two possible reasons why you may not be able to see the other participant's video:

1. The other user may have turned off their video.
2. When starting an online lesson, the online tool will run a test in the background to determine whether a user has enough bandwidth to display video. If there is not enough bandwidth available, the user will be automatically switched to audio-only in order to provide the best possible experience for both participants.
