Hi @Mark_Wooters, thanks for reaching out to us. I’m happy to help you with this, but first, some details on your setup will be very helpful. Please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.
Finally, please share a screenshot of your Device setup screen (Settings > Audio > Device Setup) for the zone that’s not behaving. and another, for comparison, for one of the zones that is.
