When you are logged in to a remote desktop, you can disconnect without logging off so that applications remain open in the remote desktop. You can also disconnect from a published application so that the published application remains open.
To disconnect from a remote desktop or published application, tap the Horizon Client Tools radial menu icon and tap the Disconnect icon. The Horizon Client Tools radial menu icon appears in the middle of the window when you are connected to a remote desktop or published application. For more information, see Using the Horizon Client Tools on a Mobile Device.
