I'm working with the SfChipGroup control and have bound an ObservableCollection to the ItemsSource property. The chip group reacts as expected when items are added or removed, however, when I replace an item the chip group is not updated. When an item is replaced in the ObservableCollection, the CollectionChanged event is trigger with event arguments containing NotifyCollectionChangedAction.Replace.
I've attached a Xamarin.Forms project to demonstrate this behavior.
