Navigation bar not displaying page title in Xamarin Forms - xamarin

Question

I have been unable to get a simple test working to display a title in the Navigation bar of my Xamarin forms app. I am providing my code below, basically when I set the title on the content page and wrap the content page in a navigation page, the navigation bar is not displaying the corresponding title from the content page.
App.cs
public partial class App : Application
{
public App()
{
InitializeComponent();
Current.MainPage = new NavigationPage(new Presentation.Views.SettingsDeviceUnitView());
}
}
ContentPage.cs
[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class SettingsDeviceUnitView : ContentPage
{
public SettingsDeviceUnitView()
{
InitializeComponent();
}
}
ContentPage.xaml
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:d="http://xamarin.com/schemas/2014/forms/design"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:Controls="clr-namespace:GFIApp.Presentation.Controls"
mc:Ignorable="d"
x:Class="TestApp.Presentation.Views.SettingsDeviceUnitView"
BackgroundColor="{StaticResource Key=ColorPrimary}"
Title="TestTitle">
<ContentPage.Content>
<Grid>
</Grid>
</ContentPage.Content>
</ContentPage>
Yet I see nothing in the navigation bar
Has anyone seen this behavior before or have any suggestions? Thank you!

Per FreakyAli's response I tested setting the navigation bar text color and I am now able to see the title. Thank you for the suggestion FreakyAli!
For reference, I added the following in my App.cs
NavigationPage nav = new NavigationPage(new Presentation.Views.SettingsDeviceUnitView());
nav.BarTextColor = Color.White;
Current.MainPage = nav;
