Books DO NOT BOOKMARK! Everytime she closes the app and reopens its at the first page.... please allow Kindle kids to sync with traditional Kindle app, or fix this glitch. My kiddo is.reading 400-500 page novels and getting massively frustrated that her page is lost every time. The books also do not display page numbers, so she needs to remember about what percent she is at and start scanning for where she left off. It's creating more frustration than it's worth.
