Question
Combining 2 systems into a single system
12 x Sonos One SL speakers split into two levels, 7 on one level and 5 on the other. I set them up as one single system and somehow now they are split into two separate systems with 2 separate playlists? How can I combine them back into a single system without having to factory reset each speaker I want to join back into the main system? They are installed in hard to reach spots.
