There is a lot of differences between the old and the new editor. I think the forum administrators should publish some sticky instructions regarding certain things that are done differently on the new builder. For instance, I spent hours to figure out how to hide a page in the navigation and link a button to that hidden page. For lack of knowledge, I made that page private and can't have access to it.
My questions are:
How do you edit a page that has already been created? How do you switch a private to a public page? How do you hide that page and still have it amongst all the pages and create a link with it?
Please, don't tell me to open up a ticket as other people might have the same problem.
