My Question or Issue

Hi,

I am trying to get local files that are saved on my desktop's spotify to download on my phone.

I have music downloaded on my laptop, saved as mp3 files that are in the music folder.

I was able to access them via the spotify app on my laptop and put them into a playlist as local files, which I am able to play, but not from my phone.

I have clicked the download button both on my phone and on my laptop on the playlist with the local files; the phone and laptop are on the same wifi network and are both signed into the same account.

I have successfully done this before using this same method (one that is posted on this website even) but I cant get the songs to download or even show up on my phone.

As a side note, the playlist consists of 20 songs that are all ~3-6 mins long but the playlist says it is something like 23000 hours long. All the songs play fine.

Cheers in advance
