I have a Beam. If I ask Alexa to play something on it from Spotify, she tells me this: "To play Spotify, link your premium account first using the Alexa app."
However, in the Alexa app, I'm linked to my Spotify premium account. And I'm signed into Spotify through the Sonos app too. She plays Amazon Music just fine and iHeart Radio, but gives me this about Spotify every time.
EDIT: I should note that I can also play Spotify just fine from the Sonos app. It's definitely an Alexa issue.
What have I done wrong here?
