Only one page is showing in webview from Google docs

Hello,

But when i make the document longer then one page it is only showing the first page ? and i can't scroll to the next page nr 2

<ContentPage.Content>
    <local:PinchToZoomContainer>
        <local:PinchToZoomContainer.Content>

            <ScrollView>
                <StackLayout>
                    <ProgressBar Progress="0.2"  
             HorizontalOptions="FillAndExpand"  
             x:Name="progress"  
                     ProgressColor="Maroon"
             IsVisible="True"/>
                    <WebView x:Name="Webview"  
         HeightRequest="1000"  
         WidthRequest="1000"  
         Navigating="OnNavigating"
