Watch & Earn mission

So this missiuon poped up and I did what it said. I logged into **Lol Esports** and started watching a game that was live at the moment. The game ended, i checked the mission but it didnt progress. Do I have to watch the game from beginning to end? Or is it just glitchy again and doesnt show mission progress?
