I'm having issues with creating a form for a document set content type. I create a new library, add a document set content type (a simple content type that inherits from the document set content type). In the library, I go into content type settings for the document set and click the Edit Form with Nintex forms link. I select create classic form.
It comes back with "Error: Cannot use Nintex forms for content type: ...."
Using Version 220.127.116.11.
Thanks in advance for any help...
