I have two Amazon Echo's set up with two Amazon profiles which are part of my Amazon Household. I also have a Spotify Family plan with two active accounts. I've tried unsuccessfully to play from one Spotify account on one Echo and from the Spotify account on the other Echo. Alexa on the second Echo plays from the Spotify account on the first Echo. This causes music interruption as you would expect.
Alexa apps are configured on separate phones with their respective Amazon and Spotify accounts. I don't know what I'm missing here.
Anyone have any ideas?
