Tv shows not syncing

When I download the app and use my trakt account, the movies sync just fine, but none of the shows sync

Welcome! SeriesGuide does not automatically add all shows from your Trakt profile. You can add the ones you want to track by pressing + and tapping Watched. For movies specific lists from Trakt are synced, so SeriesGuide knows which movies to add. But there isn’t an equivalent like that for shows.
