Hi Sonos,
I have been using sonos for over a year now for this system, it run perfectly fine but until recently:
I have few system:
1. arc + one sl x2 + sub
2. playbar + amP + sonance
3. amp + sonance
4. Few Sonos one
The playbar is always missing from the app. I have perform device and router power off for a few times to add it back. But It doesn’t fix the problem permanently as it will keep missing again.
For info, my network was setup in WiFi mesh, it’s running fine and no settings has been changed.

keith.
