I’ve used the provided remote control of my Mu-so devices first time some weeks ago. And I struggled by making use of the multiroom button. If I switch on my Mu-so 2 in the living room and press the button for multiroom nothing happens. If I go to the kitchen where my Mu-so Qb is located I can power the Qb on and synchronize it with the multiroom button to the playing content of the Mu-so 2 in the living room. But this is all. To stop this synchronization I have to switch to the app where I can uncheck the Mu-so Qb. Did I miss something in the manual?
To be honest and I really love my muso devices, but remote control is overall very poor in built quality (very sharp edges and feels haptical cheap) and it would be more useful to provide 5 dedicated favourite buttons for direct access than rather pushing the button several times without knowing if I picked-up the right preset.
