When you view the Leadership Training Library, any page, you should see a gray navbar at the bottom of the page. For some reason that no longer shows either. Instead, the entire landing page that you can click away when first coming to the library shows below any video and listing of related videos (such as the videos for elders and high priests that show segments associated with Chapter 7 in Handbook 2).
Other than this and the downloading issue, it's actually working a little better as far as performance when viewing a video anywhere within the library, this appears to have happened and probably inadvertently in the process of making those programming moves that helped make the performance improvements possible.
