You have my sincerest apologies for the delayed response here, we’ve been dealing with a higher-than-usual volume following our release and we’re working as quickly as we can to get back to everyone.
I wanted to follow up on this thread to see if you were still running into this issue on the newest build of Arc? Please make sure you’ve updated your devices and core to the latest build
From there, please head to your Roon core settings > Roon Arc, and click the refresh tab as well as ‘Reset Roon Arc’ found in your Arc settings.
