hey everyone, I've had the Kindle app on my HTC handset for a while (mainly free books), and installed the Kindle app on my N7 and logged in. however my 'store' on the N7 is empty. i would have thought i should have access to the books i've downloaded via my HTC? i've definitely logged in with the same account, because I've checked my amazon account and the 2 devices are both showing. any ideas?
