OneDrive.live.com always open in Shared folder (not Files folder)

[Chris_NH]

I pinned the Files folder in my onedrive.live.com account to the Windows 10 Start menu, and also saved this folder as a favorite in Edge, which is my default browser. But after closing Edge, when I then click the onedrive.live.com tile in the start menu, or after opening Edge, if I click the OneDrive link in the favorites bar, OneDrive opens my Shared folder rather than the desired Files folder. To see the Files folder, I can click "OneDrive" in the menu bar. Moreover, after the Files folder has been opened, if I then add a tab and click on OneDrive in the favorites bar, OneDrive correctly opens the Files folder, and will continue to operate this way (the correct way) as long as I don't close the browser. When I saved my OneDrive Files folder as a favorite in Firefox, I experienced the same problem. So the problem does not appear to be related to Edge.

How can I make OneDrive.Live.com always open in the Files Folder the first time?
