Built and ran a site in test mode with the Voyager theme. Discovered that when using the navigation icon, I could move to any subpage but no major page. The only fix I found was to duplicate the major page as a subpage. Weird - that seems awkward, and I wonder what SEO effects might be with duplication. Attached is an image showing what I had to do to make navigation work throughout the site. The user can get to What We Do by clicking on the white label, not the blue.
What am I not doing right?
