I recently got Premium and I have Spotify installed on my phone and my computer. I have saved songs to my library on my phone and they don't show up in the desktop version. Also, I just added a bunch of songs to my library on the desktop, and they dont show up on the app on my phone. I am logged into the same account, are they supposed to be seperate? Can they be synced somehow so I can find music on my pc at home then listen to it on my phone at work? I really don't want to add artists and songs on both seperatly every time, thank you.
