New Multimedia Redirection upgrades on Azure Virtual Desktop are now in public preview

Hi, for some reason, after following the steps outlined in the documentation and having the Remote Desktop Connection client reflect (insider), I can't get this to work inside of the AVD Windows 11 session host. The extension fields for "Client:" and "Host:" remain blank where I believe there should be a version number reflected. Anyone else experience this? My AVD host is currently AAD-Joined and RDP shortpath is enabled (although it still doesn't work without RDP shortpath enabled) Thanks!
