My collection


  <sho:CollectionView
      Grid.Row="0"
      x:Name="CollectionView"
      CollectionLayout="Vertical"
      ItemHeight="60"
      ItemTemplate="{StaticResource ComponentiSquadraTemplate}"
      ItemsSource="{x:Bind Path=Loader.Result, IsItemsSource=True}"/>

<DataTemplate x:Key="ComponentiSquadraTemplate" x:DataType="models:ComponentiSquadraModel">
      <sho:DraggableViewCell IsDraggable="False">
          <SwipeView HeightRequest="70">
              <SwipeView.RightItems>
                  <SwipeItems Mode="Execute">
                      <SwipeItem Command="{Binding Source={RelativeSource AncestorType={x:Type sho:CollectionView}}, Path=BindingContext.SwipeItemInvokedCommand}" CommandParameter="{Binding .}" />
                  </SwipeItems>
              </SwipeView.RightItems>
                 <Grid HeightRequest="60">
                  // some entries hereù
                 </Grid>
             </SwipeView>
      </sho:DraggableViewCell>
  </DataTemplate>

Appearing animations wokrs fine untill I remove some items from collection. When cell is swiped to the right it will be removed form the collection in the viewModel.
If I remove 3 items and than add 3 new items they will not have appearing animation, from the forth new item animation will be displayed. Basically number of removed items = number of times animation will not be displayed.
