Hi @Jeffrey_Feuer,
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.
Can you share a screenshot of one specific example of this? Do you know what tracks are missing from this playlist? Are you able to navigate to them in Roon outside of that playlist?
