My Sonos 5 stopped responding this morning - I have reset it and am trying to add it back to my account. It connected in the app, then said that the product needed updating. The process then got stuck saying unable to connect the device to my account, and i appear to now be in a loop. When I look at sonos.com I can see the 5 there, but registered 4 years ago
Just to note, I am using the latest version of the app and my Play 3 is working perfectly (as was the 5 until this morning)
