Hello @rcrawley,
Thank you for contacting Roon Support.
It looks like you’re encountering the recently discovered issue with disappearing devices, which we’ve documented here:
Audio devices disappear on Roon Server and then re-appear - Roon investigating
I’ve asked my team to enable an additional diagnostic layer on your account. Once this is in place, I’ll follow up with you here and ask that you restart your Roon Server a few times so the diagnostics can take effect. After that, I’ll provide you with the next steps.
