Every year I set myself a challenge and enjoy seeing the number of books and percentage of challenge finished rack up. All I used to do was look up a book and mark it as read, and it appeared in my books for this year and counted toward my challenge - this showed up within a few hours. It was simple and fun!
Now, however, there are other challenges within your yearly one - monthly challenges, 'epic reader' 'buzzy books' that I have no interest in. Also, I need to enter the 'date finished' every time I read a book, or it doesn't count. It also doesn't show up under 'my books' for a while, if ever (I just entered one and am refreshing like crazy but it refuses to show up under 'my books.') And it's very tough to find the 'date finished' when you're using the phone! I contacted help but they were no help - am I the only person to find the new system really clunky (Goodreads was already a pretty messy and unintuitive site to begin with)?
