I have just the same. BUT I have on my Desktop a shortcut called "Quick access", which must have been carried over from Win 10 when I upgraded. When I click this shortcut, I get a list of exactly the folders for which I have chosen "Add to Quick access" in their context-menu. Just what I (and lots of others) want.
When viewing my Quick access items, Explorer's address bar just shows "Home". If I click this, I am shown two lists of items - "Recommended" and "Favourites", neither of these is the same as what I am shown after clicking the "Quick access" shortcut on my desktop.
So it is mysterious just what this "Quick access" shortcut is pointing to -- its Properties give no clue.
