While playing songs on my phone, as soon as the screen times out - and locks (screen goes dark) - the song stops playing. Then I have to wake up the screen/phone for it to continue playing. This has been happening for months, and if it continues, I'm cancelling for good. I do NOT have this issue with Amazon Music so I know it's unique to Spotify. I already did the reatart/clear cache/uninstall/reinstall to no avail. Also, when the screen is locked there are no controls to pause, play, skip track, etc. These features ARE available when using Amazon Music, so (again) this is a Spotify-only issue. Not my phone or its OS.
