I've seen some discussion posts on here from people unable to edit or create articles - I think I can help with that! If you have the problem when clicking the green edit button or the add page button where it loads endlessly, there's a way around it. For edit, just click the arrow beside "edit" and choose classic editor. It'll load fine! For adding a new page, you just have to right click it on your mouse and open it in a new tab, and then it should work fine too. I hope this helps anybody who was having trouble with the infinite loading thing!
