Answer 1

Your screenshot shows that you don't have any documents in the Users collection. Notice how all of the document IDs are in italics, and none of them have any fields. That means there is no document there, but there is a nested subcollection under it that you can navigate into. Queries do not read any of the nested subcollections, so instead it just shows and empty collection..
