Campbell, RDR CRR CSR #13921 >Hi both! Just wanted to clarify my point in the various chats simply put, I'd like you all to lead the way here. Tell the team what the problem is, how bad it is or isn't, what areas are worth focus on vs. not I want to take your insights and then determine how to proceed. My comments in presentation were an observation that the numbers seem small but if you all say there are other ways to look at it that isn't as small or that yes its small so questioning whether we work it game. this is all fair (7/13/2022 12:10:21 PDT): >I don't want to bias or pressure us in any one direction. We are looking to you to guide us here (7/13/2022 12:10:45 PDT): >Does this make sense? (7/13/2022 12:16:20 PDT): >Yep! Georgy Volichenko (7/13/2022 12:20:30 PDT): >That makes sense and we can definitely add some numbers for late night specifically, luckily there are plenty to choose from in analysis. My point in the Leads deck chat was that if we need to explain why we chose late night and frequent use, we won't be showing numbers because that's not really how we made that decision.

(7/13/2022 12:25:36 PDT): >And product coverage was low, while competitors are making progress in this space. So those were the primary inputs to deciding late night use should be a priority area for us (7/13/2022 12:27:40 PDT): >We cited this stat in our H2 plan: Late Night: 20% of global WAU teens have a daily average of 1 session between 12 and 4am over one week.
