All of a sudden my NC will not let me put any books on a shelf. I though it was because I had used the app Goodreads, so I deleted it. But still when I hold down on a book cover and I hit to add to shelf, it comes up with a blank that says add new shelf. It doesnt list my shelves that I have been using since I bought the NC. What can I do?
Have you tried completely powering off and then back on again?
