Watch and Earn not working properly (LEC 2019)

Hey guys, I have been experiencing some issues with the Watch and Earn 1 mission for the new LEC season. I have watched all matches over 2 nights so far, but my mission keeps being stuck on 2/3 completed. I am watching through the official riot site (link in the mission), yet it hasn't completed further then 2/3. Tried watching VOD's aswell, this wouldn't give me any progression either. Anyone else having the same issue?
