Streched ActivityIndicator

Hi!

I'm truing to place my ActivityIndicator in the centre of my page.
Here is the 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"
    x:Class="CPMobile.Pages.PendingTimesheetListPage"
    Title="Timesheets">
    <ContentPage.Content>
        <AbsoluteLayout
            VerticalOptions="FillAndExpand"
            HorizontalOptions="FillAndExpand">

            <ActivityIndicator HorizontalOptions="Center" VerticalOptions="Center"
                               Scale="1" IsRunning="{Binding IsLoading}"
                               IsVisible="{Binding IsLoading}"
                               AbsoluteLayout.LayoutBounds="0.5, 0.5, 0.5, 0.5"
                               AbsoluteLayout.LayoutFlags="All" />
        </AbsoluteLayout>
    </ContentPage.Content>
</ContentPage>

Everything is fine on iOS but on Android ActivityIndicator is stretched.

What am I doing wrong?

Thank you!
