I'm running the latest PB on my iPhone 5s. Last week when I plugged it into iTunes, afterwards I noticed that there was no music stored locally on my iPhone. It like was all deleted! So it took me a whole day to get it back to normal and solve various issues with iCloud music library. Yesterday I plugged it in again to iTunes and some of my music is randomly deleted again. So I had to go in and delete all my local music then reDL it. Anyone else have this highly annoying issue?
