I have few music apps such as Mixcloud, few radio stations that after 10 minutes when the screen is off stop running. The moment I unlock my phone, the music is back. I checked the battery settings for each app allowing them to use the battery unrestricted but it didn't help. For some weird reason, Spotify works well. And if I go to the settings for apps to be put to sleep, these apps aren't on the list.

This is annoying as when I am at home I listen to the radio most of the time, but it keeps switching itself off.

Any ideas?

Thanks
