I'm losing my mind with itunes. I am not an idiot but wtf. 1) half the time when I get music and playlists on my iphone, and leave for the day, if i open itunes up on the laptop. it wipes all music from my phone. awesome. i suspect it's wireless sync is on, but why would it wipe my music? 2)is there a way to sync music that works? last night, i added a playlist to my iphone, hit sync, and boom. all music gone. WTF itunes. 3)itunes currently shows tons of playlists and albums on my iphone when i bring up the phone/music screen. is any of it on my phone / NOPE! it was there yesterday until i moved a playlist 4) today i managed to move the playlist and sync, and ONLY that playlist is on the phone. So phone has 15 songs, itunes says there are 900 that were synced. what am i doing wrong? ios 9, 6+plus 64 gb, itunes 12.4 on a mac. have always always had issues. I dont' see how if things are checked to sync, and i hit sync, nothing goes over.
