The Meeting does not support screen share

[JanEsq209]

I have the Zoom Pro plan.  I am told that I should be able to share my screen during meetings (I am the Host).

Unfortunately, during the meeting I could find no button linked to Screen Sharing.

When I tried to set a meeting to allow screen sharing I keep getting the message: "The meeting does not support screen share."  

There apparently is no such thing as Customer Support in the Zoom world and the Sales representative's advice was to uninstall and then reinstall my app.  Done + Done.  Did nothing for me. 

Any body else have this issue?  Any body know how to resolve it?  

Thanks - Janette
