CollectionView IsGrouped="True" null exception on Android

Hi!

I have a problem when in a CollectionView I assign the value True to attribute IsGrouped.

In UWP it works fine, but in Android it fails

What should I do?

I already have the CollectionView Flags configured in my MainActivity

<CollectionView ItemSizingStrategy="MeasureAllItems" 
                    ItemsSource="{Binding Modules}"
                    IsGrouped="True"
                    SelectionMode="Single">
    • • •
</CollectionView>

Thanks for your attention!!
