Some help please...Why can't I see both my Sonos speakers (Ray and Beam) that are set up as different rooms at the same time on the app? I can only see one at a time. When I’m in one of the rooms, I see that one. When I move to the other room, I have to both press the power button on the speaker and refresh the app and then I can see the speaker in this room, but the other one has disappeared. I have set up and connected both of them. Both are connected to TV’s  and work fine with the TVs. I can play music from only one speaker at a time ..when the app is connected to that speaker at that time. I want to group the two speakers together so i can play music from them both simultaneously, but the ‘group’ button/tab appears as faded light grey so is therefore unselectable (I’m assuming this is because the app is only recognising one room and that I have one speaker connected). How do I get to see the two speakers at once and have the two rooms show up on my app at the same time? Thanks in advance.
