Revelation Sound
Head-Fier
I had no issues for years but after the update, playing through the BluOS or Spotify app on 2 different phones wont play music through my stereo. I have no problem with Tidal however. I also have no problem playing Spotify through any of my wireless headphones or in the car. I let BlueOS community form know about this. Hoepfully they come out with a fix at some point soon.
