A few players have reported that auto analysis just "freezes" when it is used. As explained in the forum and in blog posts, this is because the recent updates to make it better make the server do a lot of calculations, and it takes anywhere from 10-30+ seconds for the server to return the results. So the lag is normal.
Players need to keep an eye on blog updates. Not all are relevant to everyone, but many important announcements are made.
