My Layout

Ex: Original vs Android vs iOS

What went well?
How easy is it to convert your existing ListView to the CollectionView? I was very easy. Just Copied my ListView layout from my project. Also didn't need to put a couple of options like HasUnevenRows="true". The code looks cleaner.
What didn't go well?
Did you run into any particular difficulties, and if so, what were the specific causes? I couldn't get the Pull to Refresh behavior I found here: https://github.com/xamarin/Xamarin.Forms/issues/3172 IsPullToRefreshEnabled - this is now handled by the RefreshView. But couldn't get it to work.
How is the performance?
How is the performance using CollectionView compared to when using the ListView? It seems to be the same or better.
Missing or Desired Things:
Anything? Infinite Scroll would be great to be native in CollectionView.

Thank you for your contribution. Pull-to-refresh still has to be implemented but is planned.
