Hey @Joshua_Pollak,

Apologies for the delay in my follow up! I wanted to check in to see if you were still having issues getting ARC up and running.

If so, have you tried giving your router, core, and device a hard reboot? If possible, try to access your settings in Arc and select ‘Reset Roon Arc’.

I’ll be monitoring this thread for your reply :pray:
