Citrix Multimedia Redirector fails to redirect ‘MMS’ and ‘RTSP’ links to the client. When these links are clicked inside ICA session, Windows Media Player on the client is not launched.
This issue is resolved with build 17107 and higher.
Pin prompt for Smart card authentication is not available to login into VDA session. User is prompted for “Username” and “Password” instead of Smart card PIN to login into VDA session.
Microsoft has changed the way Smart Card Service (SCardSvr) works in Redstone 4. The service will run only if a Smart Card reader is connected. As ICA sessions redirect the Smart Card, it finds the service not to be running and fails.
This issue would not be encountered if earlier Windows 10 machine with VDA installed is upgraded to 1803. For a clean install of Redstone 4, Microsoft has provided a mechanism to enable to enable Smart Card Service (SCardSvr) by adding a registry key. To add the registry key, follow below steps on the VDA:

The ‘Norskale’ key under [HKLM -> System -> CurrentControlSet -> Control] is removed during the upgrade to Redstone 4.
Citrix is working with Microsoft to resolve this issue. To restore functionality, users could uninstall WEM Agent on the upgraded machine, reinstall and reconfigure.
