Hi all, I've been searching for a similar problems but could not find anything. I send my mobi file (converted by Calibre) with the Send to Kindle PC app. I have 5 devices (Ipad, 2 android Phones, 1 Kindle Keyboard and 1 Kindle Oasis). Everytime I send to Kindle I always only send to Ipad directly so my Ipad will directly download the book and with my other 4 devices I will need to download the book manually. Lately on my Oasis, everytime I click on download, I would have 1 downloaded copy which I can read normally and the copy on the cloud would still be visible. I could even download the copy twice. This problem only occurs on some books. I have tried to send to my Oasis directly but I still encountered the same problem where my Oasis would automaticalle download the book but the cloud copy would still appear on my list. A further problem is that i cannot sync the furthest page read on these books. Again, this problem only happens to some books only. Any idea what may caused this problem? I have tried to restart my Oasis which did not solve the problem. I would like to avoid resetting if at all possible because that would mean that I would need to download all my books again. I do not have any collections either so it should not be sorting problems.
Thanks!
