So… On BTN tracker the episode that came out on November 7th is listed as part of the original series, as S09E01.
And this is how Sonarr retrieved it for me. I now see that both TheTVDB and TheMovieDB list that episode as part of a new miniseries Dexter New Blood, so Kodi scraping it as Season 9 of Dexter is basically impossible.
Any way for me to automate this? If I add Dexter New Blood as a series, no episodes are found (on BTN it’s season 9 of Dexter).
