My Question or Issue

 

So I got a bunch of local files which i imported into my playlist on PC and it works fine on PC. However, I try to sync it on my phone and it doesn't work. (Same wifi network) It says there are 30 songs which is accurate but when I click on the playlist, it's completely empty and I try downloading it and it goes through but there's still no songs. I've tried restarting my app, going to offline mode and back  and a bunch of other things but this still isn't working.

Really disappointed since I joined Premium recently and i didn't expect there to be so many issues
