Thanks, So I have added all the scripts, added the pagebuilder stuff to my start up, and added the tags to the template, but nothing shows in the pages section.
When I inspect the page in the admin, I see it has added this,
<div data-kentico-default-section="Kentico.DefaultSection" data-kentico-editable-area-id="area1"></div>
but I don't see anything in the admin, and the only error I see in the console is a missing map file.
Also, I am using content tree based routing, so I have no custom routes or controllers.
