Maybe I'm being really dense, but I can't figure out how to get books to update between my Touch and iPad. I mostly read on my Touch and if I do check the Kobo app on my iPad it's never even updated to the current book I'm reading. I'd like to get the books to be synced so that if I don't happen to have my Touch with me and have my iPad I could pick up where I left off reading. Am I doing something wrong?
