Xamarin.Forms.Maps White Screen

Hello Fellow Xamarin Developers

I am having a problem (Once again )

I am trying to show a simple map on an Android application but It the map tiles never load only google label and zoom in and out buttons

Main Activity

public class MainActivity : AndroidActivity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);

        Xamarin.Forms.Forms.Init(this, bundle);

        Xamarin.FormsMaps.Init(this,bundle);

        SetPage(App.GetMainPage());
    }
}

the code for the maps View is as follows

public MainView()
{
var map = new Map(
MapSpan.FromCenterAndRadius(
new Position(37, -122), Distance.FromMiles(0.3)))
{
IsShowingUser = true,
HeightRequest = 100,
WidthRequest = 960,
VerticalOptions = LayoutOptions.FillAndExpand
};
var stack = new StackLayout { Spacing = 0 };
stack.Children.Add(map);
Content = stack;

    }

Sir Manifest the google key value has been ommited

This isnt my first time with Maps using Xamarin but it is with Forms

if anyone can point out what Im doing wrong or if Im missing a step please do tell
