My private saved/built Sonos playlist does not play my saved songs from Amazon Music. I can go into Amazon music in the Sonos app and play all the same songs that are grayed out in my private Sonos playlist. My personal playlist with Amazon Music songs is the problem. I’m been working with Sonos Help Customer experience for the last week. They seems to be stumped. I’ve removed, reset Amazon Music, refreshed network, etc.
