Black Screen when using a Login page with Sidebar Navigation

Hi!

I'm using the Sidebar Navigation lib (https: // components . xamarin . com / view / sidebarnavigation), and here is my code snippet:

AppDelegate.cs

    public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
    {
        Window = new UIWindow(UIScreen.MainScreen.Bounds);

        if (isAuthenticated)
        {
            Window.RootViewController = new RootViewController();
        }
        else
        {
            Login screenLogin = new Login();
            screenLogin.OnLoginSuccess+= ScreenLogin_OnLoginSuccess
            Window.RootViewController = screenLogin ;
        }

        Window.MakeKeyAndVisible();

        return true;
    }

    private void ScreenLogin_OnLoginSuccess(object sender, EventArgs e)
    {
        isAuthenticated = true;
        Window.RootViewController = new RootViewController();
        Window.MakeKeyAndVisible();
    }

RootViewController.cs

    public partial class RootViewController : UIViewController
    {
        public SidebarController SidebarController { get; private set; }

        public override void ViewDidLoad()
        {
            base.ViewDidLoad();
            SidebarController = new SidebarController(this, new Home(), new Menu());
        }
    }

My Login screen is a UIViewController. The fundamental is: if user is not authenticated, so, i show the login page. When the user enter the correct credentials, i call the event 'OnLoginSuccess', that is signed in AppDelegate. So, i change the isAuthenticated var to true and set my RootViewController class as Window.RootViewController and call Windows.MakeKeyAndVisible();

When i testing this code at emulator, works fine (iphone 5s, iphone 6s+, ipad pro 9.7). But, in a real device (iphone 6 and iphone 6s) only appears a Black Screen after the login.

All real devices are using iOS 11.1 and 11.0.3.

I'm little bit frustrated.

Thanks for the help!
