I've noticed a bug in the 'recently added' category.
In my setup I am using multiple USB drives (D, E, F) for my media library, with channels server hosted on one drive - D.
I've noticed that the 'Recently Added' category for movies, only shows files that are recently added to the movies folder on D drive. This is problematic as I have stopped adding movies to this drive and now only add them to F due to capacity issues.
In short, Recently Added doesn't seem to monitor multiple source folders.
