I have an iPhone and Sony Android TV. I've never had this issue before, but in the past few weeks I am having trouble staying connected to my android TV spotify app. I can connect to the TV w/ the 'Connect to a device', however, I notice that if I don't touch my phone for a while, when I go to unlock my phone the spotify box on the lock screen will not be there. Then when I go back to the app it's often at a completely different song than what my TV shows, and if I click next it will stop spotify on the TV and only play on my phone, so then I have to reconnect to continue playing.
Does anyone know why spotify seems to disconnect from the phone but continue playing on the TV or how to fix this?
