CC libraries panel not loading in XD
I'm learning to use XD with the approved Classroom In A Book for XD from Adobe. All going well until I reached the section on adding assets to a Creative Cloud Library. It says to go to File and then Open CC Libraries but if I have a document open this doesn't appear in the menu and if I just launch XD it appears in the menu but is greyed out. How do I get the panel to load? The section deals with adding an asset from an XD document to a library. It's doing my head in...
