Is it possible that I am misunderstanding the function of the preview? Is it supposed to show the user what the site will look like when the page is published? Or maybe that it just shows the page how it would look published, without the context of the section that it will be published in?
I am hoping that one of these is the case, does anyone have it working so that content that uses overrides and displays with custom templates displays properly when pressing the Preview button in the admin?
