_"There was a problem marking this watched." _
This is the error I get when I try to mark an episode manually. Automatic marking after watching or scrubbing does not worked. This is true of ALL files AFTER a particular date in November. The date may coincide with a software update.
Steps I have taken:
Made sure I'm running the latest stable release
Rescanning the entire library, updating all the metadata
Re-added clean files to library.
Manually renamed files already successfully identified for metadata matching to strict naming standards
Doing the above and then re-adding to library deleting the prior version
Purchasing and using Filebot to do the same to make double-darn sure filenames are not an issue
Deleting and rebuilding the library
Still no joy.
