Weird 3D touch behavior - 3D touch no longer working after opening the app

I added a 3D touch shortcut to my app. When I try it on device, i would get the behavior I want when I try first time. When I open the app, do something, and quit, and try 3D touch again, it won't do the thing I want it to do.

func application(application: UIApplication, performActionForShortcutItem shortcutItem: UIApplicationShortcutItem, completionHandler: (Bool) -> Void) {
    self.handleShortcutItem(shortcutItem)
    completionHandler(true)
}

func handleShortcutItem(shortcutItem: UIApplicationShortcutItem)
{
    switch shortcutItem.type {
        case "com.loafer.start":
        self.presentConfigureViewController()
        default: break
    }

    }
func presentConfigureViewController()
{
    guard let navigationController = window?.rootViewController as? UINavigationController
        else { return }
    let identfier = "ConfigureViewController"
    let ConfigureViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier(identfier)

      navigationController.pushViewController(ConfigureViewController, animated: false)
}

*ConfigureViewController is the view controller I want the shortcut to navigate me to.

Update: I am wandering why no one is answering my question, so sad. Do you guys need me to provide additional information? Just leave a comment.
