So I had a Sonos One set up with Alexa and it was named "Office". I bought a Sonos 3 for that room and named it "Study", moved the One to the bedroom and have been trying to rename it "Bedroom" instead of "Office". I've renamed it in the Sonos and Alexa apps. When I do that the name is correct but if I close the app and open it again the name goes back to "Office". It's not a massive issue but it's got me puzzled and i can't work out how to fix it. Any ideas?
