Hi @Karl_Mayhew,
We had a brief issue that our team has resolved today — You should be able to find this without issue now.
Downloading tracks from a streaming service for offline play does not work in Roon. If you purchase albums from Qobuz and download those that will work, but content available from your subscription cannot be played offline.
So we can better assist you, 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.
Do you experience with with any other zones?
