First off, if a problem occurs during a session the first action to take is to refresh the internet page.
Make sure that you are in an area with a strong connection. Using personal data could make the lesson dip in and out of connectivity.
The whiteboard works on all browsers but it works best on the latest versions of Google Chrome or Safari.
Ensure that your Microphone and Camera are working. This should be tested when entering the whiteboard through a set of various test stages. Permissions for camera and microphone must be enabled in your browser. To toggle these you will need to head to your browser settings/preferences and for more instructions click here.
Some older tablets do not have the capability to join the whiteboard. Recent iPads and android devices should be fine.
Occasionally school intranets may not allow the use of the whiteboard, this could also be the case for internets with various blocking systems.
