I have followed https://learn.pimoroni.com/tutorial/sandyj/streaming-spotify-to-your-pi several times on my Pi3 with no joy.
Iris installs, everything looks good, except the following message under Spotify:
Connected (Mopidy-Spotify extension not installed/enabled!)
I have reinstalled raspbian a few times as it seems every time I make a change to the mopidy.conf file, it then breaks Iris. For example, I read that I need authenticate mopidy with Spotify via: https://www.mopidy.com/authenticate/#spotify But when I add it to the [spotify] section of mopidy.conf under /etc/mopidy/ it dies.
Any help for a total noob would be greatly appreciated.
