Downloaded kindle books lost after hard reset
I have a bunch of books in my kindle library and had downloaded a subset of them to my iphone in the kindle app.
I was having issues with the iphone, and I ended up doing a backup/hard-reset/restore. Everything came back fine except my downloaded kindle books. Actually, when I first opened the kindle app, I saw the previously downloaded books listed in the "device" tab, but they soon disappeared.
Where does the kindle app store this info on my phone and why wasn't it saved/restored to/from the backup?
I can download those books again from the cloud, so nothing lost, but it is an annoyance - especieally if one likes to have lots of books handy.
Thanks.
