Trakt TV not working

I have had the trakt tv set up for a while - it has worked intermittently for movies - but has now stopped syncing.

TV shows don’t sync either.

The folder that contains Movies is set to media type Movies and the TV shows folder is set to media type TV. The Trakt tv add-on has been logged into and set to scrobble and sync.

ATV is not showing up under the “connected Apps” under my account.

Is there something else that I should be looking at?

Does this have anything to do with the new pin requirement when setting up Trakt on 3rd party apps?
