Thanks @antoviaque - if you can see my previous posts in this thread, I followed the instructions in Enabling Public Course Content — Latest documentation to set the instance flag and then set the visibility in my courses on training.openedx.io (Sumac) but I’m not actually seeing any public content, so I am wondering if the feature works.
But… huh. It works for this course: Course | but not the Demo course. I wonder if something else needs to be enabled or something?
