title: Xamarin Forms - Menu issue when navigating from Content Page to MasterDetail Page
body: <p>When trying to navigate from a Content Page to a MasterDetail Page the menu icon does not appear. Although, if i first load my MasterDetail Page the menu icon is there as tis supposed to be. The menu functionality is not affected. Working on Xamarin Forms but the problem occurs only when debugging in Android device.
  Any idea about the icon?</p>
  <p>Load instantly MasterDetail Page using <strong>MainPage = new NavigationPage(new MainPage())</strong>

  Load from Content Page (LoginPage) using <strong>MainPage = new NavigationPage(new Login())</strong> then when a button is pressed navigate to MasterDetail Page using <strong>await Navigation.PushAsync(new MainPage(), true);</strong>
