Folders

[Efficient_Good_5784]

It is intentional that the "folder" button isn't shown with Android TV client?

I believe so.

We don't recommend folder view to be used because it's not an actual folder view of content located on your library directories.
It's actually a folder view of how Jellyfin has its things sorted in its database.

There hasn't been much work put into it, so folder view will be buggy.
We don't recommend it for that reason.

We always recommend people to stick to a proper TV or Movie library depending on their content.

If you want a library closest to folder views, I would make a music library as that would be the closest thing.

Also keep in mind that not all clients support the same library types.
