Can't get into Onzoom class

I signed up for a On.Zoom class that should have started 15 minutes ago and getting a warning saying "Waiting for the host to start this webinar" - I have contacted the host, but I was curious if there were any troubleshooting issues that were on the Zoom side as apposed to the host side.

I have downloaded all of the most current updates, so I should not have any issue getting in - right?

Thoughts?
