Hi @jamie, thanks for the response. Yes, it’s as you say. We have created 2 service tickets for this problem (Non-functioning Roon after the last update build 1211 (02/2023) and After new update roon is slow ). We have 2 cores with Roon rock connected independently to a central NAS with a music library on a single Ethernet network for two users within the home. The problem with the Roon system occurred with both Roon systems at about the same time after upgrading to the latest Roon software version. I can also confirm that I have contacted the dealer in my country and he is also addressing this issue.
