[ NEW ] Windows IT Pro: Getting started: Windows Virtual Desktop ARM-based Azure portal

A great walk through, thanks much! I am able to Sign in in the Webclient, The Remote Desktop client however fails. The error mentions https://mrs-prod.ame.gbl/mrs-RDInfra-prod that the Organization has not subscribed to or enabled. In previous blogs on this I see this URL in the App Registration in Azure AD. With this deployment the URL is empty and I am not able to fill out the URL Field (in the GUI). Any suggestions?
