Just updated to iOS 8.0.2 on iPad 2. Storage changed from 40GB available on iOS 7 to 21GB availabe on iOS 8. I expected iOS to take up more storage on iOS 8 but not that much. I noticed that in Video App on iOS 7 even cloud streamed videos would show up as taking uip storage (music also), but could be deleted in settings usage to increase available storage. Cloud streamed videos in iOS 8 seem to decrease available storage also, but Video and Music Apps no longer show in settings/usage to delete files (will show if physically downloaded), and cannot be deleted within apps themsselves. Has anyone noticed this problem? I have also deleted unused apps and files, but no significant change in available storage has resulted. What else is using extra storgage is unknown.
