I have found that expand to open folder is working in some cases but not others.
If I start in the This PC section of the navigation pane, it works.
If I start on a folder that is pinned in the Quick Access section, it works with some folders and not others. All of the pinned folders for which it works are subfolders of C:\Data (a folder I created), and the ones for which it doesn't work are subfolders of C:\users<username>.
