iPad kindle app syncing with kindle last page read
I have the kindle app on my ipad3 and I have the kindle which I do most of my reading on, but occasionally want to continue reading the same book on my iPad. However, when I open the book I've been reading on my ipad it doesn't pick up where I left off from my kindle. Why is this and how can I get it sync? What have I not done right?
iPad (3rd generation) Wi-Fi, iOS 5.1
