Sorry to create a new thread on this, but after a search I couldn't find an answer (or remedy) for this problem. So activated iTunes match lat night, everything went well. Logged on to my 4S, activated the service on this end, and after hesitantly swiping yes to "this will erase all local music and replace with iCloud music" I accepted. The music took a second, but then all songs (including ones not previously stored on my device) showed up. Thought success, but then realized that ALL the playlists were gone, and in its place was "Add new Playlist". This of course freaked me out, but then after 5 min or so, the playlists were added back. Now the reason for the message is that that was last night. This morning, opened the Music app and again the playists were gone. After another 5 (seemed longer this time, but on my work wi-fi which is much slower than my home network) minutes things came back, of course not after chewing through 4-5% on my poor battery life that remains a problem. Is this going to happen EACH and EVERY time the app is closed and reopened? Could it have something to do with a sync that occured over wi-fi last night while sleeping and phone plugged in? Any solution for this or is Apple even aware?
