The Roon @support team prefer one topic per customer’s issue… so they are able to track it and focus on each individual problem. hence I split out your topic.
In order for Roon’s @support team to better assist you, please provide a brief description of your current setup and the nature of the issue using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so they have a clear understanding of how your devices are connected.
Rebeka - This has been solved. I got community advice to just download the 880 Remote version from the App Store, rather that wait for an auto-update or notice within Roon that an update was available. My 2 devices were an iPhone and iPad.
