My documents show that I have started 4 of them, but when I click on Documents none of them show, it just says I haven't written anything yet.
My documents won't show up!
Hey there! Make sure it says "ALL UNIVERSES" under Notebook.ai in your sidebar. Since documents can now be added to universes, the document list will also be filtered whenever you focus on a specific universe. That means only documents added to that universe will show in your document list. To see them all, you can flip back to "All universes" and/or add them to whatever universe you're focused on.
I'll add some kind of notice soon to make this more obvious it's what's happening. Sorry about the confusion.
