The last update broke leaderboard creation for Daily Runs, which caused them to appear empty for everyone. Since the run results are stored locally for a week, they can still be uploaded with this update. Just start the game and enter the Daily Run menu. Your runs from the last few days should appear on the leaderboards as usual. If you don't see them immediately, just wait for a while, go back to the main menu and re-open the Daily Run section.
Sorry for the inconvenience and thanks a lot for the continued interest in Daily Runs everyone!
