I have tried to delete a Qobuz album. I get the message that it is deleted but it’s still there but unplayable.
Having the same problem; rebooting core should clear it, but this needs the attention of Roon support
Then it needs to be posted in Support
Did you try adding the ‘favorite heart’ in Qobuz’ app for that specific ‘zombie album’ subsequently removing it in Qobuz, while your roon server is down or not having any connection to your Qobuz account?
This helped in several cases.
Go to Album → Edit → Rescan and try again to delete. This helped on my side
Thanks for the suggestions. I’ve fixed the problem now by stopping and restarting Roon Server. I’ve got it installed on a NUC whch I only use for media. When I looked, there was a Norton screen telling me I should do a scan. It looks like Norton was interfering with the Roon setup.
Thanks again. I appreciate the help.
