  There was a problem communicating with the server. Get-AppLibAppVPackage : The maximum message size quota for incoming messages (41943040) has been exceeded. [LD0232]

• When using the PowerShell command get-brokericon -filename with the -servername parameter, the command returns an error message. [LD0324]

• The Citrix Virtual Apps published applications might not enumerate intermittently. As a result, a blank screen appears after the session starts or the applications fail to start. The SQL server might experience high CPU usage and the SQL Monitor might show blocked and expensive processes. [LD0336]

• The Citrix Universal Printer object is created with the EMF Universal Print Driver inside a session even when you set the Universal Print Driver preferences to XPS or Native drivers. To enable the fix, install the Citrix Receiver for Windows 4.9.5000 LTSR Cumulative Update 5 or a later version. [LD0360]

• The resource utilization data in Citrix Director might not be sorted in the correct order. The issue occurs when the SQL statements are presented in the wrong order. [LD0388]

• When you start a session, the broker might choose newly created VDAs over VDAs that were previously started. This choice can cause increased logon time. The increase occurs when the selected VM does not complete the post startup operations before the VM receives a session request. [LD0511]

• After you rename an application within the application properties and then attempt to remove the Delivery Group from the application in Citrix Studio, this error message appears:

• Citrix Director might show incorrect user connection failures when the FailureDate column for sessions is set to Null in the MonitorData.Session table. As a result of this failure, the failure types are not updated in the MonitorData.ConnectionFailureLog table. There is a mismatch in the connection failure value that is retrieved from the Monitor Database and from the Get-BrokerConnectionLog output that is pulled from the Site database. [LD0726]

• If the .vhd extension is present in the upper case (.VHD), the VHD picker might not detect it as a valid vhd image. The issue occurs when you create a Machine Creation Services catalog in an Azure environment. [LD0746]

• The identity disks might be removed from the Machine Creation Services (MCS) that are present in the Amazon Web Services (AWS). [LD1043]

• When using applicable product releases, the administrator might not be able to create a host connection in Studio if NSX-T networking is enabled in the VMware environment. The issue occurs when the MCS does not enumerate the opaque network in NSX-T. [LD1102]

• The HDX connection logon data might be missing from the Logon Duration graph. [LD1113]

• The CreateNewInstanceOnReset is decommissioned and is no longer operational. The VM is always preserved when power cycling or when updating a machine catalog. [LD1114]

• There might be a delay of several minutes when you restart a machine while using Amazon Web Services (AWS). [LD1220]

• When the CopyFileWithRetries function fails to copy a file in a directory, the remaining files might not be copied. The issue occurs when the Citrix Profile Management service attempts to copy files from a default template profile directory to the current user’s profile directory. During the copy process, the corresponding function CopyDirectory ends the copy operation when one file under the current directory can’t be copied because of permission restrictions. As a result, other files aren’t copied. [LD0648]

• The VDA for Server OS is running on Microsoft Windows 10, Version 1709 or greater. When you choose to exclude the *.tmp file for synchronization of Profile Management policy, the changes you make to any Microsoft Office documents, such as Word and PowerPoint files, might not be saved while you log out. Your changes are not retained when you log on and reopen the files. [LD0782]
