WebView Inside a ScrollView not working

Hi,

I have a simple WebView inside a ScrollView but the problem it's not scrolling anything.

here is my code:

<ScrollView Grid.Row="0">
    <Grid Grid.Row="0" RowSpacing="0">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>

        <SyncfusionRotator:SfRotator x:Name="RotatorAdDetails" Grid.Row="0" EnableLooping="False" EnableAutoPlay="False" NavigationDelay="4000" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">
            <SyncfusionRotator:SfRotator.HeightRequest>
                <OnIdiom x:TypeArguments="x:Double" Phone="300" Tablet="400" />
            </SyncfusionRotator:SfRotator.HeightRequest>
            <SyncfusionRotator:SfRotator.ItemTemplate>
                <DataTemplate>
                    <StackLayout ClassId="{Binding user_guid}">
                        <FFImageLoading:CachedImage Source="{Binding media_file}" ClassId="{Binding ad_guid}" LoadingPlaceholder="AdPlaceholder.png" FadeAnimationEnabled="True" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" Aspect="AspectFill" DownsampleToViewSize="true">
                        </FFImageLoading:CachedImage>
                    </StackLayout>
                </DataTemplate>
            </SyncfusionRotator:SfRotator.ItemTemplate>
        </SyncfusionRotator:SfRotator>

        <WebView x:Name="WebViewAdDetailsDescription" Grid.Row="1" Margin="5" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" />
    </Grid>
</ScrollView>

How can I fix that please?

Thanks,
Jassim
