It seems I need to open the book twice to get the correct page. Let's say I open a book and read until page 50. If I exit the book and reopen it, it will open to another page (say page 21). I have to then exit the book and reopen it for it to open at page 50. This bug is repeatable. That is, at this point, if I exit the book again, reopening it will open it on, say, page 21. Then I exit and reopen and it will reopen in page 50. I've already tried to reinstall app and account repair.
