Hi, usually it happens if you have device that already connected to Shairbridge. I mean you have 2 iPhones and got connected iPhone 1,now with out disconnecting iPhone 1 you are trying to connect iPhone 2. I saw it many times in houses with few kids, they never disconnect their devices and don't remember who played last and ....... Usually if you can find connected device and disconnect it, or just reboot MAIN controller, it should help, but it helps only ones, it can happen again and again.
For those cases I make custom button "Reboot Controller" so nobody needs to go and to play with power cables.
If it is not an issue..... you need to talk to your dealer.
