I'm trying to figure out why some movies don't appear when calling the changes endpoint https://api.themoviedb.org/3/movie/changes.

For example, the movies https://www.themoviedb.org/movie/1184030-generation-change-who-saves-the-world and https://www.themoviedb.org/movie/1184035-die-kriegszeit-rund-um-st-ruprecht-raab have been added on 2023-09-26.

They don't get returned in any page

curl -H 'content-type: application/json'  'https://api.themoviedb.org/3/movie/changes?api_key=<API_KEY>&start_date=2023-09-25&end_date=2023-09-28&page=<X>'.

also not with different date ranges.

Are there additional requirements for a movie to appear?
