Yes, there is an issue between Crestron and Sonos, but it has nothing to do with the S2 or S1.? Basically, over time, the system errors out and looses connection.? To get it back, the processor will need to be rebooted.? I have many many systems out there and it seems like the larger the system the quicker it has issues.? I have some small ones that seem to work just fine, even with the errors.? I have larger ones (25-30 devices) that seem to only last a few hours before needing the processor rebooted.? I have one system 24 devices that I had to put in programming to reboot it at midnight and at 5:00 in the afternoon just to keep it from going offline.? The main error that I see is

Error: splusmanagerapp.exe # 2020-09-29 03:36:55? # [WebSocket]<00000000> WebSocketClientConnect: Error: ipaddress lookup by hostname failed

The system will start getting these and after some time, eventually disconnect from the Sonos.

Not sure this will help you, but I thought I would send it for informational purposes.
