Add a library filter on the Kindle Fire App to only show books in a particular collection
There's a previous question like this with 76 votes that says "Completed. This suggestion was implemented in version 8.4.0 of the mobile apps." But this is not available on the latest version of the App for the Kindle Fire. The only filters available are "Sort by Title," "Author," "Rating," and "Recent," and doesn't show my collections in the library. I only see my collections in Search.
