When I play a song from the Spotify iPhone app, the sound will go quiet for 3 seconds then restart again. I have power cycled everything including the router, didn’t help. All the system is up to date, I just checked. Besides, this has been going on for months - if not years.
More in general, I noticed there seem to be a conflict between the Spotify app and the Sonos app. It almost looks as if they are both wrangling for control and conflict arises.
Help much appreciated!
