The review for the all-in-one dashboard has been postponed until the next sprint with Media Viewer focus.
I'm not sure why it stopped updating, but performance was probably a factor since it looks like it was taking 7+hours to run the database queries. By working with Sean Pringle from Ops, I was able to get indexes added to the table with the worst performing queries. Now most queries are fast (2 minutes at most). Except the global actions one, which still takes a very long time due to the sheer amount of data it's dealing with (calculating figures on 120+ million rows). We should be fine for now.
