My Question or Issue

I have some local files that I am able to play on desktop version of Spotify. I then created a playlist and added those files to it, and they could still play on my desktop. However, when I open the mobile version and attempted to play it, all I could see is that the song is being greyed out and I am unable to play it, even though I was on the same network and enabled the 'download' function, which is working perfectly as the songs offered by Spotify was able to be downloaded. I had also uninstalled and installed the app, but the problem still persists. What should I do?
