CollectionView item does not immediately reflect changes on screen.

I have an ObservableCollection of products in a CollectionView. When I click the like button, the like count is increased, but the change does not reflect on the screen immediately until I scroll the item off the screen and then back and it shows the increment. How do I make this increment reflect immediately without scrolling off the updated item. That is equivalent of NotifyItemChanged in Xamarin Android. Thank you.

    Sounds like the binding is wacked.
    You don't normally have to do anything to get an update.
    But its not INotifyItemChanged - Its INotifyCollectionUpdated since it was an item within that collection that changed.
    You can run through the 2018 or 2019 tutorial series here
