Hello. I am pulling the collection data with the link below.

https://www.themoviedb.org/collection/9485-the-fast-and-the-furious-collection

For example, there is incoming data on this page. They are not coming. Earnings, Featured Lineup and Featured Team are not coming.

https://api.themoviedb.org/3/collection/9485?api_key=[api]&language=tr-TR&append_to_response=credits,videos,release_dates,external_ids&include_video_language=tr

The API does provide all of the information you can see on the website, the extra data you're looking for is not available on the API.
