On my windows 10 system, when I press the play/pause button on my keyboard, nothing happens to the playback. Space bar and ^P will work if the app is selected (in the foreground), but those are useless if you are using the app in the background.
I checked on my windows 10 phone as well and the behaviour is a little bit better; the Bluetooth headset's play/pause will only work if the media being played is an audio file - but it will still not work on a video.
Is this something that we can fix please?
This is impacting use of the HTPC scenario with a universal remote control.
