I'm re-posting this in the hope that someone may have a clue to the solution, please.
Having been very disappointed to find that there is no Alexa link to my music library, I was hoping that Spotify would give my wife an easy way of playing the music she enjoys. Instead this is proving very frustrating.
Alexa on my Sonos One will not play music from Spotify. It responds "to play music from Spotify link your premium account first using the Alexa app"
I have a Spotify "premium account" in its trial period so haven't paid anything yet.
All Sonos devices are listed in the Alexa app: playing radio works OK
Spotify is set as the default music service in the Alexa app
Sonos skill is enabled
Do they both have to be registered to the same e-mail address?
Do I have to wait until I'm paying for Spotify?
