I have two Sonos Ones in my Sonos setup. They've been fine since I bought them soon after release, but over the last week or so, they keep renaming themselves to "Default Room". My other Sonos speakers do not rename themselves (several Play:1s and 5s). So far they've renamed themselves 3 times over the last week. I rename them back, but within a day or two, they're both back to being called "Default Room".
I assume it's something to do with their Alexa integration? (given that it's only the Play Ones effected). Any idea how I can fix this? It's really irritating as once they've renamed themselves, it's difficult for me to figure out which speaker is which.
