In the RadListView, after adding a ListViewPropertySortDescriptor, if the property of the ItemsSource object which is used by ListViewPropertySortDescriptor.PropertyName changes , the ListView would be reordered automatically on WinUI, iOS and MacCatalyst. However, this does not seem to be the case on Android.
In addition, on iOS and MacCatalyst the sorting does not apply as expected. The sort order is wrong. 

Workaround: Use the direct properties from the model and add/clear the descriptors when property you sort changes.
