I've been using my Amazon Echos to play Spotify for about a year. Suddenly, it's not recognizing my Spotify playlists when I tell it to play "playlist name". I'm using the same syntax as always. I have multiple Echos and they all do the same thing. It will either say that it can't find the playlist or suggest a different playlist.
I confirmed that Spotify is my default music account. I tried disconnecting and reconnecting my Spotify account. I also tried renaming playlists.
