I believe @amr008 has done the exercise of mapping the prices to engagement. However, you are absolutely right in saying that the engagement went down to almost 50% lesser than previous month. The real worry is the active members on the platform have reduced drastically. So when users go down obviously the engagement goes down but the silver lining is that existing users engaged more with the community and the average number of interaction every active user performed was almost 25% more than the previous few weeks.
