Up and up - for the US, who eventually pulled through to win all categories (Gold/Silver/Bronze/Total) despite some extremely subpar US performances (ahem, Men's Track).
USA!!! USA!! USA!!!
If you are asking about a specific app/presentation, you'll need to be more specific (e.g. YTTV still shows the current medal count).
On the main Roku menu, under "Home", there's "2020 Tokyo Olympics". Before today, when you went to that Olympics selection, it showed the medal count on the right side of the screen (and then the videos/channels after you clicked the right arrow) . Now, it shows the videos/channels immediately and no medal count. The medal count has been there from the beginning - until today.
Good question! I am also wondering where it went?
