So happy to. I'll break down to a couple of pieces. So with regard to the first half, it goes back to something we've talked about a bit on this call, which is very simply, we have the total ad supply and inventory, which is tied to our user growth, but also decisions around frequency, depth testing, ad load. And we have never increased our halo over the last couple of years and it's really been come through organic feed item views. Now as we've talked about, we are going to test the different ways we can do things that might affect supply, less frequent or more dynamic notifications, certain dynamically changing ad load. Thinking about those types of dynamics will affect the total supply. But as I mentioned earlier, that is intentional. Now that does mean that as we flow that down through the model, that will constrain growth more than it would have, all else if we just proceeded with our continued optimization through the quarter. So a lot of it really is tied towards those changes, those optimizations, those tests. And that's why it is linked to that effort to drive towards the next mid-2025. As we move into the second half of the year, we'll be looking closely to see where those can start to drive things like supply growth, user growth, and we'll certainly share more on those as we go. And then as it relates to large advertisers, it is certainly, as I mentioned earlier, making it easier or present to buy. It's also making sure we're continuing to deliver performance. And so there's been an effort that's been underway and continues to progress, which is making sure those larger advertisers, including ones with whom we have a more active relationship that they are getting benefits from our ad server as well. And so the same way our self-serve advertisers are seeing leverage and better performance from the ad server, we're going to make sure that our larger advertisers see those same benefits, and we're continuing to march as expected through that ad SAC transition. And so when you pair that with the going-forward efforts around programmatic partnerships, and really just a focus on helping them reach the audience and evolving our go-to-market. We think there's an opportunity. It's not something that will change in a quarter. But in conjunction with Next, in conjunction with the new ways of buying we think there's a real opportunity to show progression here over the course of the full year.
