Whenever I launch a specific book on my iPhone or iPad, it says that I'm not at the latest position and asks if I want to go to that position. The problem is that reported position is invalid (e.g. 999999). If I choose to go to that location nothing happens. Since I can not go to a further location, the last reported location is never updated and I cannot use this feature on this book.
I'm looking for a way to reset this furthest location without it erasing my notes and bookmarks.
Since this happens on all the clients, I am assuming it's not a problem with the individual clients and instead is a problem with the web service.
I tried using the directions on http://www.mobileread.com/forums/showthread.php?t=84601 but since I don't own a Kindle, it doesn't work.
