Shuts off when you close screen

Like many others have said I use it to sleep at night and have loved it, but after the new update when I close the screen it stops playing the sound. You either have to leave your phone screen on all night or no sound. App is useless now. Hope they fix it or Ill have to uninstall and look for another option. Wish Id read reviews before updating -_-
