For the past couple of weeks, the Spotify app on my Logitech UE Smart Radio has been failing. The app recognizes my account, but won't display my playlists. I can search for titles, artist, and albums, and I can get the app to play songs, but it doesn't see my playlists, which is a new behavior. I've been using this app for several years without trouble. I have made no changes to my UE Smart Radio settings or firmware that might explain the problem. I have uninstalled the app, reset it, even reset my UE Smart Radio to its factory settings, but the problem persists. Any suggestions?
