Any ideas why my collectionview will not scroll when using scrollToItemAt. It wont even let me manually scroll it up, it will just bounce back down on its own like the insets are not adjusting for the keyboard being there. I put a print statement inside handleKeyboardShow and it prints whenever the keyboard is opened so I know the function is being called.

Brian, do you have any tips that I can apply to make the scrollItemAt method work if I am using a view controller containment pattern?

I fixed the my scrolling issue by creating a collection view controller instead of embedding a collection view in a parent view controller. Like Brian mentioned above, the scrollToItem method does not work, or i could not get it to work when the collection view controller is embedded in a parent view controller. hope this helps anyone confronting the same issue.

Hi, anyone know how to paginate when using a snapshot listener? It doesn't seem to work for me using my normal method of pagination.
