I have downloaded two songs in .mp3 format and they have transferred from my files on my MacBook to my local files on Spotify. The songs show up on the playlists I have added them too on my MacBook app, however, they do not show up on the iPhone app. I am able to "play" the songs on my iPhone but only if start playing them from my MacBook and then listen to them on my iPhone. If I try and add the songs from there it is okay and then move them to a playlist the "this song is a duplicate" message pops up but the songs cannot be found on my iPhone. Both the apps are up to date, MacBook and iPhone are up to date, I have logged out and restarted both the apps and the MacBook/iPhone respectively, the wifi they are connected too is the same, but still nothing. The only thing that I find odd is that there is a grey (white?) circle with a downwards facing arrow next to these two local file songs but I cannot click it (pic included). Any help would be much appreciated (and hopefully this is not a lost cause).
