It works correctly on my newer devices like Oasis, Voyage, fire6. But on my older stuff like K1, keyboard and old basic, it shows like 2 or 3 books. I have lots more than 2 or 3 on there.

. I wonder if it has to do with the cloud stuff that came about with the paperwhite. Older devices don't use that new cloud collection system.
As long as it works on the new devices I use now, I am good. Its kind of neat. I went through the Oasis and Voyage and because of the ease of seeing the titles, I moved a couple of books up on the tbr pile. They kind of got lost in the shuffle I guess. I didn't even remember I owned them.
