New to Trakt, add all my local show to collection

I have set up plex scrobbler but it only show up in my collection after I watch it.

Is there anyway I can add all the show I have into the Trakt collection? I tried to remove and re-add the plex libraries but nothing were added.

Those are separate actions, so Plex should be sending webhooks for each. There is a long standing bug on the Plex side that doesn’t send collection info if more than 1 episode of a show is added to the Plex library at the same time. Maybe that’s the issue?

Thanks, but shouldn’t that work for movie as well? Is there any one way I can add those to my collection as a one off action?

You could use an app like GitHub - Taxel/PlexTraktSync: A python script that syncs the movies, shows and ratings between trakt and Plex (without needing a PlexPass or Trakt VIP subscription) to sync all your data over. The web hook is only a real time action from Plex, there isn’t a way to send existing data over. This is a limitation of how the web hook works.
