RDP function using the Viewer does not work for me at all. The Viewer is a Win10 Pro machine, and the Host is a Win7 Pro machine, both running latest beta, 18.104.22.168. RDP did not work either before the beta upgrade, on version 22.214.171.124, by the way.
I can connect just fine using Windows RDP app from the Viewer machine to the Host machine. I checked and made sure that RDP was allowed on the Host machine. When I click on RDP in the Viewer, nothing happens. I verified that the RDP port setting in the Viewer is correct, I tried with Direct Connection checked and unchecked.
Also, in the Properties, the Configure box is cut off - see screenshot link below.http://imgur.com/a/g9YWg
