I’m not sure if this feature is still working but it was working for me in the past. AFAIK, the disk rescan interval is every 12 hours. I deleted the first episode of Minority Report since last week but I noticed that in the Sonarr GUI it is still listed there. Manually rescanning/updating series info in disk did unmonitor that episode though. So it seems that the auto rescan is not working.
How do I troubleshoot this?
