It is worth noting that the issue is intermittent. It does not happen every time I start a new session, but it occurs often enough to be noticeable.
I have already tried disabling and re-enabling Last.fm scrobbling by removing my account details from Roon and then re-adding them. I have also restarted the server multiple times.
The issue does not appear to be tied to a specific endpoint. It happens across all endpoints I have tested, regardless of whether I am streaming locally on the LAN or using ARC while away from home.
I am hoping there are logs or additional diagnostics that can be enabled to help identify the cause. That should allow me to either resolve the issue on my end or raise it as a bug if needed.
Thanks, please let us know when it happens next with the rough timestamp and track name. That will give us something specific to look at, and we can take it from there.
