Since I updated my iPhone 6+ to iOS 8.2 the music library continually vanishes from the device. The bizarre thing, when the phone is plugged into the PC it shows all the music there, if fact I can play it from the device. This usually happens as I'm trying to add more music etc, and so far only a full erase/restore has resolved it. I have done a full wipe and restore 3 times now, even had the device replaced by Verizon and it is still happening. As I have over 60GB of music on the device it's a real hassle to continually have to restore it. Has anyone else experienced this and more importantly found a fix?
