ipod touch not syncing with itunes
I have the latest iPod touch connected to iTunes on a windows PC.
The music syncs fine including pushing new songs from iTunes to the iPod touch and playcounts coming back to iTunes.
I have updated many of the Apps on the iPod but these are not coming back into iTunes so iTunes is showing 40odd apps as needing updates.
Any tips on how I can get this working?
I have tried restrictions and they are not turned on.
Thanks.
iPod touch, iOS 8.1.3
