When I tap on the hamburger icon, I only see the options in the Top
Level, and by Top Level I mean the top row in the content map. So that
means I do not even see Collection B in the hamburger menu dropdown,
since it is not part of the Top Level. With the collection in the Top
Level, the first item is an article, but when I select that collection
from the hamburger dropdown, it displays as a browse page, even though I
set the view settings to Content View.
