I need Trakt to delete automatically some movie or tv show of collected when I mark it as watched but idk how someone pls help me
The best way is to find the movie/tv show by searching for it.
Tap on collected
It should clear
They delete it automatically from your watchlist. I don’t think your use-case is supported as most people don’t want to automatically clear their collection
Plex Trakt Sync on github would probably do what you need
This is correct. Collections are for those that want to keep track of what they have actually purchased (hard copy, digital copy, etc). I think what the original poster is asking for is exactly what you mentioned. Watchlist is what they needs to be using for this functionality.
Maybe the OP just doesn’t know how to use Collections and/or (personal/private) Lists since they are different than Watchlist (even though that’s a list, it’s a dedicated list that can’t be deleted because of this kind of functionality).
This functionality is what the Watchlist is for, not Collections. Collections are supposed to be for movies/shows you have physically purchased (including digital versions).
