If you're seeing a toolbar like this:
This means you're an unapproved user, and your admin will need to approve you. Your admin if most likely whoever signed up first. More info on that here.
If you're an approved user but a feature is missing:
This means your toolbar isn't at the most recent version.
Usually the toolbar will update automatically. However, some practices find they have trouble getting our updates.
We've built a tool called our Utility tool which does a full repair and will bring in the latest version of the toolbar. You can run it following these steps, and it should get you sorted!
NB you no longer need to be an approved member to use the video feature.
