So in 3.x if you go to Integration > Mura all you get is a message on the page
"The Mura CMS Integration has been enabled for this Slatwall Instance."
Not exactly sure what the point of that is. If you go to settings > integrations > mura you get some more options but there are missing display values and errors when you go to edit them. (see attachment)
Sorry for playing dumb here but I am trying to go through the docs. Since upgrading I have basically lost my products displays and everything I had worked on (i know they are still there somewhere) but I need to get this back so I can keep moving forward.
