so as far as I can tell with all my apps having background app refresh turned off Spotify almost immediately after I updated now will start to heat up my phone quickly after starting any tracks and then the app crashes approx 3 minutes later.  

i have tried to heat my phone up other ways with games that are graphics intensive but nothing heats it up as fast as the new update does. 

I’ve tried listening on other apps, watched YouTube, Reddit, Twitter all open and none of those heat my phone up. 

even listening to a video or a stream while playing a game doesn’t heat my phone up. 

something Spotify did to the app in this update has completely broken it.
