The ability to switch between the classic and the new version is missing. I am in the dashboard, and the "Join Options" section is just gone. I sued to be able to switch between the classic and new at will, I was doing so for testing, we want to switch all employees now to the enw version but suddenly the function is missing.
I found some troubleshooting suggesstion which said that the admn may ahve disabled it, I am the admin, didn't disable anything. And if I have accidentally I cannot find a way to enable this feature.
