Edit post sends the user to either (1) standard WP dashboard editor or (2) an Easy Admin page with the announcement, "Whoops! This function is not available in the Easy Admin area. You'll have to switch over to the Advanced Admin area to access this page."
Does this mean that you can't edit posts with Easy Admin? You have to use the dashboard editor?
I can't predict which of these - 1 or 2 - will happen with a given post.
