You can switch between Horizon Client and other apps without losing a remote desktop or published application connection.

Horizon Client suspends data transmission when you switch to another app. Data transmission resumes when you switch back to Horizon Client.

By default Horizon Client runs in the background for up to three minutes on iOS 9.0 and later devices. After three minutes, you can resume Horizon Client and continue using the previous remote desktop or published application session without having to reenter your credentials. You must reenter your credentials only if the server's session timeout, or idle session timeout, limit is exceeded.
