I was able to link Spotify and Voice Assistant Alexa through the Alexa App.
However, I can’t play Spotify through “Alexa, play __ in Spotify”. It will respond, “Ok Playing...”, but then there’ll be nothing playing.
I found a Sonos support page to try to disable Sonos Skill in Alexa and then re-enable it again. I tried that, but after click on Enable, I get this error from Sonos API page:
Register your speakers
You need to link speakers to your _____ Sonos account before you can add this skill.
But I have already linked my speakers to my Sonos account and I can see it on the Sonos app.
