I update yesterday to 8.4.1 and now I can't add my songs from my library to iphone 5c, or remove them via itunes. I turned off Icloud library and apple music and have tried to reset the phone several times. One time it looked like it would work again, I could drag a song to the iphone, but when I tried to drag several more it didn't work. And the song I dragged is just greyed with a dotted circle and isn't showing upp on the phone so it didn't really work It has worked in 8.4 with apple music on, I didn't change any settings after updating. Sync music is off. Nothing happens when I drag songs over the iphone, no blue outline and number of songs dragged. As you can see it's just grey. On the picture I've tried to drag a song and the mouse is over the first playlist. I should be able to add a song like that, as I always have, right? I have no idea what to do. I did restore the phone from a backup made yesterday,but still the problem persists. I can't find any answer on google. I have no idea what I can try more than completely wipe the phone and start from scratch.
