Have a series 5 Samsung TV with Spotity. Have connected at Bluetooth speaker, UE Ultimate and all sound plays through the speaker (TV, Youtube etc) apart from the Spotify music. When you go to the Spotify app, you can see the music is playing however no sound. When you disconnect the speaker the sound plays through the TV. You can see on the iphone app the Spotify playing through the Samsung TV. Hope someone can help please!
