Hi Jeff,

   There is a catch, we also need to create a broker access rule, post that I can able to see Weblinks published content.

 

Create Broker Accessrule for above delivery group to define user assignment

 

Get-BrokerDesktopGroup |fl name, Uid

 

New-BrokerAccessPolicyRule -Name "SPA-DG_Direct" -Enabled $true -AllowedUsers Filtered -AllowRestart $true -AllowedConnections NotViaAG -IncludedSmartAccessFilterEnabled $true -IncludedUserFilterEnabled $true -DesktopGroupUid 13

 

New-BrokerAccessPolicyRule -Name "SPA-DG_AG" -Enabled $true -AllowedUsers Filtered -AllowRestart $true -AllowedConnections ViaAG -IncludedSmartAccessFilterEnabled $true -IncludedUserFilterEnabled $true -DesktopGroupUid 13
