PocketPedia only syncing some covers (iOS 8.0, iPhone 6)

[Tybee]

So I just upgraded to an iPhone 6. When I restored my iPhone backup to the new phone, none of the Pedia art was there. To force it to re-download from my MacBook Pro, I deleted the app from the phone, reinstalled, then tried to sync over wifi. I disabled Auto-Lock on the phone, since I know from experience that locking the phone interrupts PocketPedia syncs, and knew these syncs would take a long time (~900 book entries, ~500 CDs, etc.) The apps found each other, popped up the permission window on my Mac, and began syncing, but at various points would just quit without bringing over all cover art (which I've carefully tended over the years). Have tried several times with similar results.

This is very frustrating, so any recommended fix would be appreciated.

Hold down the Option key when tapping the sync button, as described here.
