Xamarin.Forms 标签页错误

Question

I have created an application with Xamarin.Forms for android and ios. On android everything works fine, but i have a little problem with ios. My app contains a TabbedPage that is composed of two different tabs. Each tab is a content page and it has a listview inside it. This is the code:

<TabbedPage 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"
         x:Class="MyApp.Views">

<TabbedPage.Children>
    <ContentPage x:Name="page1">
        <ContentPage.ToolbarItems>
            <ToolbarItem Icon="more.png" Clicked="ToolbarItem_Clicked"/>
        </ContentPage.ToolbarItems>
        <ListView ItemsSource="{Binding JobsToDo}"
                  x:Name="listView"
                  VerticalScrollBarVisibility="Always"
                  RowHeight="240"
                  SeparatorColor="Transparent"
                  BackgroundColor="#fffffd"
                      SelectionMode="None" ItemTemplate="{StaticResource startJob}" />
    </ContentPage>

    <ContentPage x:Name="page2">
        <ListView 
        ItemsSource="{Binding JobsEnded}"
                  VerticalScrollBarVisibility="Always"
                  RowHeight="240"
                  SeparatorColor="#4b4b4b"
                  BackgroundColor="#fffffd"
                      SelectionMode="None" ItemTemplate="{StaticResource endJob}" />
    </ContentPage>
</TabbedPage.Children>

The problem is that second ListView in "page2" is frozen and I can't scroll it. ListView in "page1" works correctly. I've noticed, that when you use TabbedPage on IOS with 2 or more tabs and one of the tab contains ListView, then ListView is also frozen. Is it a bug or I've done something incorrectly? Please help me

I found solution to my problem. I've updated XF from 4.7 to the latest and everything works correct now on both platforms.
