I would like to remove the old cruft that shows as collected when I no longer have the shows or movies, and I would like to restore the shows I do have that I removed from trakt manually and then re-added some time later.
Essentially I would like a fresh rescrobble of my collection.
Is that possible from my account or would that require assistance from Trakt support?
Answering my own question with a simple enough workaround.
Installed Kodi and pointed it to my TV Shows folder. Corrected a handful it got wrong, and scrobbled it.
Now trakt is showing series I had manually removed in the upcoming calendar, and it is not showing airing episodes of shows I had remove from the library.
