We used the sleep timer every night to turn off the sound in our bedroom, then it was just gone when the app updated. One of the updates said the sleep timer returned and every once in awhile we would stumble across it but it never made sense when it appeared or didn’t.
Finally figured out that it only shows up when you are playing a music source and not when using line in. So now every night I have to mute the sound, change my source to music, set the the sleep timer, switch back to line in, and unmute. This is a ridiculouse work around, when is this feature going to be fully retored? This equipment is way to expensive to be dealing with an app that should not even be in production!
