I have 6 devices set up. One bar, two Ones and three play:3
Bar is hard wired in.
Once a week or so, atleast one of the :3s and the Ones will disappear. I can find them in missing products.
I solved for wireless interference. Wi-Fi on channel 7 and Sonos on 11. Worked for a few days.
I’ve done system reboots on individual devices and all the system updates.
What else can I try?
