As the moderators helpfully noted above, the issue with Qobuz items disappearing is related to known failure. There is a dedicated tracking thread above in @Geoff_Coupe’s post.
As for ARC, we can see authorization failures in recent account diagnostics.
In most cases, this means that ARC has lost its session-layer authorization with your current RoonServer instance, either because of a server a) migration b) backup restore or c) inactivity.
You can resolve with a simple reinstall of the ARC app. Please let us know if this helps. For future reference, there’s a ticket in the pipeline to prevent these session failures due to inactivity moving forward. This should prevent the condition long-term after a couple release cycles.
Please let us know if this helps, and we can either merge your thread or split into a dedicated thread to troubleshoot your ARC issue accordingly. Thanks!
The message on Arc reads: “There is an issue with your Roon server. Your Roon server is online, but there’s an issue that’s preventing access. Go to the Roon app for more information.”
But there’s no information on the issue on the Roon app.

As a next step, could you please head over to your Roon Settings>Roon Arc from one of your Roon remotes, and see if you have the purple check mark, or if there is additional diagnostic information to share?
