Looking back all my manual updates to the library after updating to PlexMediaServer_1.11.0.4666 seem to be a wasted effort. I’m using the same format for files as prior to the update. I keep updating and currently am using Version 1.11.2.4772.
Attached logs
I uninstalled 1.11.2.4772 and resorted to QNAP original Version 1.10.0.4523 and it found all my episodes.
