So I can sync great between my Mac and iPad. My iPhone will not get syncs unless I turn off iCloud music sync on my phone and turn it back on and it grabs the updated list (and all others). Anything else I can look at on my phone?
A lot of people are experiencing this - I believe I saw someone on Reddit say that it's a bug and Apple's working on it. For me I can make changes on my iPhone and iTunes recognises them, but not vice versa... So for now I'm just doing everything on my phone, though it's a bit of a pain.
Just came for that same reason. It's a pain to have to download music when I just want to update a song or two to a playlist. The syncing should be automatic.
Also is there a way to see what songs are not downloaded yet? I know the little device icon should be over the song if it is downloaded, however, that icon is only showing over a few of the downloaded songs when a lot of songs have been downloaded.
