iphone6plus, ravnokar ponovno naložil zadnji ios in nato restore. 1x so se ibooksi uspešno zalaufal, nato pa so je ibooks začel sesuvati tako kot pred restorem. in to sesuvanje mi gre že počas na živce.

kakšna ideja?

in še nekaj me zanima, če ponovno naredim clean install in nato set up as new iphone, kaka nazaj na ip6 naložim vse fotografije ki sem jih posnel s telefonom..

sem probal tole in "zaenkrat" še čudežno deluje.

I Had the same issue, got a senior tech support guy named Will on the phone, dude is a genius. Here is what he had me do, no issues since.
go to your settings, and first go to Safari and delete your history by scrolling down to "clear history and website data". Then go to the advanced settings and select "'website data". It should show 0 bytes. If not, clear again.
next go to iTunes and App Store in settings, and touch your Apple ID, the select sign out.
AFter you you sign out of your ID, restart your iPad by holding down the power button and home key simultaneously until you see the apple logo after the restart.
when you are powered up, go to iBooks. You should get a message that you need to sign in to sync up your books. Sign in, and that should do it.
apparently what happens is there are two things, somehow safari history affects their native apps like iBooks and iTunes, and second, iBooks gets out of sync. You can't delete the app anymore, so you have to clear safari then reset iBooks in that order.
good luck, and if you can't make it work, tell them you want Will, the senior advisor in the mountain time zone to help. Sorry, don't have a last namel beth
