I can't transfer purchases from my iPad to a new computer
I can't transfer purchases from my iPad to a new computer. The option to do this in File>Devices is greyed out. I've authorised the new computer and am also using the correct account on both my computer and my iPad. Is there an easy way to transfer the songs on my iPad to my new computer? The computer I previously used to sync my songs is broken so I am unable to use it.
iPad, iOS 8.4
