Linux clients don't show up as local devices on home network

[windyoutside]

Hi,

I'm trying to sync a playlist using "Local files" located on my computer onto my phone. The suggested way to do this is to connect both the computer and phone to the same WiFi network, and then to toggle the "Download Offline" option on the phone.

When I do this, the phone says "Waiting for download." I think what's happening is that this relies on both the computer and phone showing up as "local devices." As a debugging measure, if I check the "Show local devices only" option on the Android app, then my computer no longer shows up as a device I can connect to (though our living room speakers do, which suggests the issue is with the desktop client rather than the Android client).

I've installed the latest version of Spotify on both mobile and computer.

Thanks in advance for your help!
