The new version 6.0.5, on an iPad with files loaded onto the iPad (using iMazing, maintaining the file’s creation/modify dates!)
The “Library” view shows both Movies and TV Shows “Recently added” and “Unwatched”, but the newest ones no longer appear first (i.e. the files with the newest creation dates no longer appear on the far left of each list).
I don’t know what order they’re displayed in. At first it seemed that the oldest was first, but that’s not true. Movies show up sometimes with newest left of a given movie, and sometimes the older dated movie is to the left.
Therefore, the Library views to find newest not watched OR newest added movies and TV is now utterly useless.
