I have just replaced my two JBL link with Google assistant by two Sonos One.
With the JBL I used to ask Google assistant to play music for a certain duration and it worked very well.
Now, when I ask the same to a Sonos One, it plays for the requested duration and then, Google Assistant says "excuse me, I didn't understand". And it continues to play.
Are there kind of limitations with the Sonos devices?
