@yesiam_a_pirate What OS is your ROON core running on? Are you up to date on the latest version on both your Core and Client.
Normally you do not need to reboot after an upgrade. I had to once a few years ago.
I setup ROON and Qobuz at a friend's place yesterday and it worked perfectly. This setup was on a MAC. My home setup is on Windows.

BTW - for any ROON experts, can you run the ROON client on Ubuntu? Maybe using Docker if not native to Linux?
