CMS365 saves all its information in SharePoint libraries.

If you navigate to any CMS365 resource directly, you will normally be redirected into the CMS365 landing page.

You can block that redirect by adding the following query string to your page: ?disablecms=true

This will allow you to view the document library directly, where you can use OneDrive sync, view version history information and other information that CMS365 isn't exposing.
