I've put two speakers in the everywhere group via the app on my phone and I want to play music from an external hard drive randomly, but the same track to both speakers. I say 'Alexa open my media on the everywhere group' the one that is within listening distance to me, then plays a track randomly as wanted, but the other speaker isn't playing, so I then say the same command within listening distance to that one, and that speaker then also plays a random track from the hard drive.
How do you get both speakers to play randomly from the hard drive, but the same track at the same time please?
