Itunes 12.3.1 not syncing music with Iphone 6 IOS 9.1

Hi everybody,

My name is Paul and I'm having trouble with syncing my iTunes with my iPhone.

Up until recently it was working fine. Then I noticed this problem yesterday where none of my new music was syncing with my iPhone and all the album artwork from my phone is gone aswell.

I tried the following:

Restarting computer

Updated iTunes

Restored iPhone to a previous backup

Un-ticked "Whole music library, syncing, then tick it again"

Any help is appreciated!

Sincerely,

Paul

iPhone 6, iOS 9.1

If syncing isn't working as it is supposed to the following steps should work:

Backup your device
Restore as a new device
Restore the backup made earlier

A feature introduced with iOS 9 referred to as app thinning or app slicing allows each device to download only the code and resources needed by that device, resulting in smaller downloads and better use of storage on the device. As a consequence the device no longer holds the universal version of the app that could be installed on any device so transferring apps is no longer supported. Hopefully Apple will make some changes to the way this works, but in the meantime you can download past purchases from iTunes and/or enable automatic downloads of app purchases to make sure that iTunes always has the apps that you want on your device. As long as you make sure all apps are present and updated in iTunes before attempting a restore there should be no loss of data. I can't confirm, but it seems a recent update means that all data is restored and apps that are not in the library are queued for download from the iTunes Store over Wi-Fi, in a similar fashion to the way restore from iCloud works.
