Compared to: Citrix Workspace app 1912 LTSR CU6

Content Redirection

  • When Desktop Viewer is set to full-screen mode and the default browser is maximized on the endpoint device, the Bidirectional Content Redirection feature might not bring the local default web browser window to the foreground. The issue occurs with local default web browsers other than Internet Explorer.

Logon/Authentication

  • Attempts to add Citrix Gateway URL might fail intermittently with this error message:
    Authentication Service cannot be contacted.

Session/Connection

  • Using the Storebrowse utility to enumerate resources for the Citrix Gateway URL might fail when at least one of the configured Delivery Controllers is not reachable.
  • When Citrix IME is enabled, certain third-party applications might not respond and application launches in a user session might fail. The issue occurs because of the faulting CtxIme module.
  • Attempts to refresh or launch an app might result in the cannot contact store error message. This issue happens when the retrieval of shortcut description for specific subscribed apps fails.
    Your apps are not available at this time. Please try again in a few minutes or contact your help desk with this information: cannot contact store.
  • Attempts to launch a user session might fail after using the selfservice.exe –init –ipoll –exit command.
  • With this fix, you can set TWITaskbarGroupingMode to GroupNone either in HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE. The TWITaskbarGroupingMode key is available under, for example, HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\Seamless Windows.

User Experience

  • When the Build to lossless graphics policy is enabled in a multi-monitor environment, spanning the screen across a laptop and an external monitor might result in a distorted image.

Compared to: Citrix Workspace app 1912 LTSR CU5

Client Device Issues

  • In a Citrix Workspace app session, starting a YouTube video or a Microsoft Teams call and then disconnecting the headset might make the session unresponsive.

Installing, Uninstalling, Upgrading

  • When you upgrade Citrix Workspace app for Windows from Version CU4 to Version CU5 without installing self-service, the following prompt might appear:
    Upgrading from Unsupported Version
    Citrix Workspace will automatically uninstall your old version and delete all your settings, which you can restore later. Otherwise you will have to delete everything manually. Click OK to continue.

Logon/Authentication

  • Logon to Citrix Gateway using an incorrect password lets Storebrowse make multiple authentication attempts that might lock out the user account.
  • Citrix Workspace app authentication might fail after initialization when attempted using a smart card through Citrix Gateway. If you refresh the authentication process after 15 minutes, a 404-error message might appear in the embedded browser within Citrix Workspace. This results in the app being stuck in the authentication loop until you close and reopen the app.

Session/Connection

  • Opening a published application using folder redirection when the folder redirection share is offline, might fail with the following error message.
    Unable to launch application
  • When attempting to open an application using the shortcut with the Limit to one instance per user and vPrefer options enabled, a connection failure error might appear on the Citrix Director.
  • During a conference call, when using Microsoft Teams in HDX™ optimized mode, the video portion of incoming calls might flicker.
  • Citrix Workspace app might poll external beacons for internal stores. With this fix, external beacons are not polled when the store is used without the gateway.
  • Shortcuts for published applications through Citrix Workspace app cannot be created without appropriate permissions. As a result, the icons might be downloaded in the user profile at every refresh, increasing the cache size on the endpoints and the CPU consumption in the StoreFront side.
  • An optimized Microsoft Teams peer-to-peer call made from Citrix Workspace app for Mac to Citrix Workspace app for Windows might disconnect.
  • Launching sessions from Delivery Groups with an access policy rule specifying the client IP address might fail if the client has multiple NICs.
    Rule: Set-BrokerAccessPolicyRule -Name <rulename> -includedClientIPs <Client ip address>

System Exceptions

  • Citrix Authentication Manager (AuthManSvr.exe) might exit unexpectedly during logon.

User Experience

  • When you open a desktop window in windowed mode in a multi-monitor environment, the following behavior might be observed.
    The window opened on monitor 1 and dragged to monitor 2 might appear maximized on monitor 1 instead of on monitor 2.

User Interface

  • With this fix, you can switch to the required account when multiple accounts and the current account registry are configured.
  • Configuring an enabled and a disabled store together using a Group Policy Object might result in a non X1 or a green bubble user interface instead of an X1 user interface for the first time on the enabled store.
  • Disabling the store account in Citrix Workspace app might not delete app shortcuts from the Start menu or the desktop.

Compared to: Citrix Workspace app 1912 LTSR CU2

Installing, Uninstalling, Upgrading

  • When you attempt to refresh Citrix Workspace app by using its shortcut that is created manually, the shortcut might get deleted and then recreated.

Keyboard

Logon/Authentication

  • Even after you enable the keep me signed in and don't ask again for 60 days policies, Microsoft Azure Multi-Factor Authentication might still prompt for authentication.
    Note:
    We recommend that users exit their stores rather than log off from their stores. If users log off from stores using webview authentication, they might be prompted for authentication again because Internet Explorer cookies are cleared in such scenarios. By default, the fix is enabled (cookies are stored). You can disable the fix by enabling the Prevent storing persistent cookies GPO policy under Citrix Components > Citrix Workspace > User Authentication. If you disable the fix, the cookies are not stored and are cleared during logoff. If you disable the fix, the cookies are not stored and are cleared during logoff.
  • On Azure Active Directory (AD) joined devices, when Citrix Workspace app attempts to access a store and then passes through endpoint logon credentials, users might not be authorized to log on. Also, there is no option to log on with a different user account.

  • You configure Citrix Workspace app for Windows to connect to all store accounts when establishing a session. If you log off from Citrix Workspace app and log back on, the store account setting changes to one store account rather than defaulting to all accounts.
  • With the bidirectional content redirection policy enabled, attempts to redirect a URL from a client to a VDA might fail.
  • In scenarios where proxy servers do not use port 8080, Citrix Workspace app might fail to connect to published applications and desktops. The issue occurs because Citrix Workspace app for Windows might fail to use the proxy port and use the default port 8080 instead.
