My daughter was round our house for Xmas and used her Spotify, on an iPhone 6S, to create a playlist over my SONOS Play:1. The next day, when she was at her own house, 4 miles away, she was trying to use her Spotify to play over her own Bluetooth speaker, unfortunately my Play:1 started up on its own, and as the Bluetooth speaker wasn't responding she tried increasing the volume, yes you guessed it, the Play:1 began blasting out with the music she was trying to play! I have a Play:1, Play:3 and Play:5, with the Bridge, can anyone suggest how this could have happened?
