Module 2 Debrief milestone task #2 not unlocking

The milestone task #2 is not getting unlocked even after completing the milestone task #1 for 2nd module. I have passed all the test in assessment as I can see them in assessment tab. But didn’t receive mail for that. I am stuck there and cannot move forward. I tried logging out and in. I tried clearing cookies. I tried reloading the browser. Nothing is helping.
