Unity ads dashboard is not working , what does this mean ?

Have you already launched your game? If not that´s the reason. Ads can only be played when the game is built. Inside Unity you will always get Test-mode screens. Just export your game and play it a few minutes. The data on the dashboard gets refreshed on the next day, so that could be a reason for this error too.
