I see in the answers there's supposed to be a way to upload your own mp3 music into a spotify playlist. But none of the ways it says to do it are current anymore or don't work on web player. They all say to go to some sort of "settings" tab, which I don't see anywhere. One answer, when I click on the local files help topic and click through to desktop, closest to what I have, being not the app, it still talks about the app, and shows it looks like a down arrow. I don't have this. My three dots don't have settings either.
Am I looking in the wrong place or does this not exist on the web player? I use spotify on my chromebook, which uses the web player, not the app, is that the problem? It seems strange there wouldn't be a way to upload files from desktop to your spotify, and the web player seems like the way you use it on desktop. Is this only available for premium? If so it should say so in the instructions for uploading local files.
As you can see, I have no down arrow like the official instructions for local files upload shows.
