These instructions work on an iPhone. I can't figure out how to do it on the computer, but what they say is correct. If you want to rename a TITLE of a notebook, all you have to do is go to the notebooks (not the specific one but the list of all the notebooks). In the top right corner, you will see three horizontal dots. If you touch those, you can "Edit". Touch the notebook you want to rename and then rename it. If you want to delete the notebook, you can either press the red circled minus sign to the left of the notebook name or swipe from right to left when you have the list of notebooks up.
