That's a bit of a joke for a system marketed as multiroom but hey ho.
It's also saved me the expense of buying 2 Pros (assuming they do the same) as the only reason for me getting them was so I didn't have to keep toggling Amazon HD on and off when going between single device and multiroom.
I'm not so bothered about multiroom quality as it's not critical listening so I'll just use my Echo Dots for that instead ... shame.
@WiiM Support @WiiM Team ..... Is there any chance of getting this resolved?
