There is a problem when I use discover api getting movie info.Here is my request:

https://api.themoviedb.org/3/discover/movie?include_adult=false&include_video=false&language=zh-CN&page=1&primary_release_date.gte=2025-04-02&primary_release_date.lte=2025-04-30

I get 55 total_pages and 1098 total_results. Then I add region param, here is new request:

https://api.themoviedb.org/3/discover/movie?include_adult=false&include_video=false&language=zh-CN&page=1&primary_release_date.gte=2025-04-02&primary_release_date.lte=2025-04-30&region=CN

I still get 55 total_pages and 1098 total_results. It seems region param does not work. So as with_release_type param.
