Weekly TFT mission (level 6 by round 11)

How do I get this mission completed? I've done many rounds getting to level 6 before round 11 and it has never counted.

We're testing a new feature that gives the option to view discussion comments in chronological order. Some testers have pointed out situations in which they feel a linear view could be helpful, so we'd like see how you guys make use of it.
