Go to the Manage Your Kindle page on the web, and navigate to the list of your books. Find the book you want to reset. Click the icon with three dots next to the book title. Select “Clear furthest page read…. ” And you’re done.
The next time you open the book, the furthest page read will be set to the current page on that device.
Jonathan Strange & Mr Norrell is a novel with footnotes. You can read the footnotes by just tapping on the screen, but I made the mistake of going to the footnotes section in the back of the book. Since then then remember-furthest-page-read feature has been broken, making it inconvenient to switch off reading the book on my Kindle and iPad. But now that’s fixed. Nice!
