Web player no longer works on Chromium with user-agent switcher

[joulusoturi]

I got Raspberry Pi 3 running raspbian. I've been using Chromium with a user-agent swicher to be able to use Spotify web player. Now it just tells me to "Enable player in your browser" and directs me to these instructions: https://support.spotify.com/us/using_spotify/system_settings/enable-the-spotify-web-player/

Wich basically tell me to go to chrome://settings/content and tap a setting under Protected content. The problem is that I don't have a Protected content section in the chrome://settings/content.

EDIT: If it matters, here's the user-agent I use: 

Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239 Safari/537.36
