I have 4 Sonos One’s (one with Alexa in garage) and a Connect Amp.
I told Alexa “Alexa resume” and speaker in another location started playing.
The speaker with Alexa had nothing cued to play, so for some reason it started a different speaker.
I cued music for it, played, paused, and told Alexa to resume again and the one in the garage with Alexa did resume.
Never used to do this. If nothing was cued, Alexa would just do nothing.
This could be serious if it played music outside or in a room where someone was sleeping.
