Cannot add manually synced songs to a playlist with Apple Music songs
I'm hoping someone has battled with a similar issue to what I am having!
Currently, I have Apple Music and use iCloud music library. I generally download for offline playback, and add individual songs to a mixed playlist (which also had songs in it from before Apple Music came around). I manually synced an album that is NOT on Apple Music to my phone (iPhone 6) and added it to its own playlist - all good so far.
The problem arise, however, when I try to add any of these songs I manually added to the mixed playlist - Music gives the tick and says added to playlist... but then it immediately gets removed from the playlist as if I never added it. I 100% cannot seem to get around this despite my best efforts, and syncing the phone with iTunes simply removes random songs without warning (as I am sure you have all experienced).
Does anyone have any similar experiences and/or solutions?
