Questions about collections

Greetings.

Question about Collections.
With the same settings on tvOS and iPadOS/iOS, the collections are not the same: most of them are the same, but some collections are not available either on Apple TV or on iPad.

And the second question.
My media is set to Russian, but many films have English descriptions and posters. How to fix?

Collections can either contain synced items or streamed items, but not both. So, if you have created a collection for items that are stored locally on iPad, those collections will not be available on Apple TV.

Infuse uses https://www.themoviedb.org for all movie and TV show data. If a title does not have a Russian translation available, then English metadata will be displayed.
