Hi since I upgraded to the Xperia 5 from the XZ2 compact I have been experiencing problems with Spotify, once I lock the screen it will only play for 10 minutes at a time then it turns off and I have to unlock the screen to start it again. It also does the same when I'm playing the downloaded music thought Spotify, I have looked at all the settings for the phone and the app and I can't find what the problem is. Ian
