• When there are two or more stores in StoreFront, clicking “Configure Remote Access Settings” on the first or second store might duplicate that store name on the most recently added store. [LC8089]

• When you configure stores with shared authentication in StoreFront, attempts to link a new NetScaler Gateway appliance to a store can cause the existing NetScaler Gateway appliances that are already linked to be removed. When you attempt to log on to the stores, the following error message appears:

  “Your logon has expired. Please log on again to continue.”

  Additionally, the StoreFront console shows duplicate store names. [LC8219]

• When importing a store with HTML5 configuration using “Import-STFConfiguration” PowerShell command, import might complete successfully. However, attempts to launch an application using Citrix Receiver for HTML5 fail. [LC8290]

• The StoreFront server might show null entries for Receiver for Web sites in the console. The issue occurs when the store name begins with the text “discovery” in the URL. [LC8320]

• With the W3C logging service enabled, attempts to make changes to the StoreFront configuration might fail and the following error message appears:

  “An error occurred while saving your changes.” [LC8370]

• With local app access enabled, using the interactive logon disclaimer policy can cause the desktop viewer to show a gray screen when connecting to a VDA. [LC8136]

• When using applications that use a redirected webcam, such as Skype for Business or a VLC media player, the webcam might be redirected and detected during an initial session launch. However, when you reconnect to the user session, the webcam is no longer detected. Instead, a gray screen appears in place of the video preview. [LC8588]

Smart Cards

• When you log on to a session using a smart card, the session might become unresponsive until you disconnect and reconnect the session. [#LC8036]

System Exceptions

• The wfshell.exe process might exit unexpectedly, pointing to the taskbar grouping module. [LC6968]

• With the USB redirection policy enabled, VDAs might experience a fatal exception, displaying a blue screen with bugcheck code SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (7e). [LC7999]

• On VDA 7.12 or later versions, when you attempt to suppress the display of the language bar in a seamless session by setting the seamless flag to “0x00040000” (disables the language bar agent) under the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI, the language is no longer hidden. [#LC8349]

Session/Connection

• Attempts to reconnect to an application might fail. The issue occurs when any of the disconnected applications became unresponsive when the session disconnected initially. [LC6550]

• When you click “Cancel” on the progress bar of a session launch, wrong session information can remain on the Delivery Controller. As a result, the actual session is not created on the VDA and you might not be able to launch a new session. [LC6779]

• The microphone might be redirected intermittently in the user session even after setting the “Client microphone redirection” policy value to “Prohibited.”

  This fix addresses the issue. However, if you continue to observe the issue, apply the following registry key on the device with the microphone:

  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\ica-tcp\AudioConfig; Name: MaxPolicyAge; Type: DWORD; Value: Maximum time (in seconds) allowed between the last policy evaluation and the time of endpoint activation. Default is 30 seconds.
  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\ica-tcp\AudioConfig; Name: PolicyTimeout; Type: DWORD; Value: Maximum time (in milliseconds) that the system waits for policies after determining that the policies are not up to date. Default is 4,000 milliseconds. When the timeout occurs, the system reads the policies and continues with initialization. Setting this value to (0) bypasses the Active Directory policies check and processes policies immediately. [LC7495]
