No devices found in sonos 2 app, but i can find them no problem using sonos 1 app but it tells me i need to use sonos 2 app.  but i cant discover any products using sonos 2, only sonos 1.  ii have restarted everything, redownloaded sonos 2 app, and internet works great.  Only 1 WiFi network in the house and all connected to the same one.  
 

any advice would be great!
