Hi @David_Shore ----- Thank you for the report and sharing this observation you have made with us. The insight is appreciated.
Moving forward, we have found that Meridian endpoints are stable for many of our users and as you mentioned in your post, the “12 zones of Meridian Sooloos devices” are stable in your store, so let’s try to figure out what is different about your “personal” setup.
With the above in mind may I very kindly ask you to please provide further insight into your setup using this link as a guide and furthermore, would you kindly also expand on the details of your network configuration/topology. I want to have a clear understanding as to how your various devices are communicating with Roon/your network. Having insight into the networking hardware (i.e make/model) and what the chain of communication looks like would also be very helpful.
Lastly, please also be sure to provide the firmware versions of your various devices.
