Shweta, it's Tony. I'll start, and Ravi, feel free to chime in. On the first question about the accelerated growth at bigger scale, look, a lot of these improvements and developments were the results of our team's work, probably dating back a couple of years ago. I've always believed that it's very, very difficult to make changes, especially at our scale that can have material impact within a short time period, whether it's the quarter or even the year. And in many ways, that goes to the work that we do today, which is the work that our teams are working on right now likely will have an impact on a quarter a few years into the future. And I think if we're doing our work right, that is always going to be the cadence here at DoorDash, where the North Star focus is always to make improvements, first and foremost, to our products, to the selection that we offer of both stores and items, to the affordability of those items and stores, the quality of delivery, the timeliness, the accuracy and certainly, the customer service, especially when we get things wrong. And I think that's been a consistent narrative that reflects a consistent execution at the company for the 12 years that we've been doing this, and it remains to be the case today. So we've seen improvements across the board in our various products that have achieved the results that you're seeing today. With respect to the second question on ads, you're right, at some point last year, we did cross $1 billion of revenue run rate in the ads business, making it the fastest in history to get there. And I mentioned all along that the ads business has been progressing really healthily. But the focus for the ads business today and 3 years ago when we started the business and in the future will always remain the same, which is we have to achieve the best consumer experience and build the most successful marketplace, which is what will enable us to build the most successful return on ad spend product or the most successful advertising business for retailers, CPGs and restaurants. That remains the focus. With respect to Symbiosys, an acquisition that we closed, one of the developments we've always had is that we've always been privileged where there is more dollars that advertisers want to spend with us than we are willing to give in terms of the surfaces in which we allow them to advertise. Again, we're trying to make sure that we have a best-in-class consumer experience. And therefore, whether it's compared to peers or just compared to what we think the right thing to do, is we don't allow advertisements to just show up in the products. That doesn't mean though that there isn't a good use of dollars or proceeds from these advertisers. This is why we purchased Symbiosys, where together with our know-how as well as our information that we collect, we believe that we can be the best marketer. You can almost think of it as we are the agent of choice where we can do the best marketing spend for each one of these merchants and advertisers. A lot of times, I think when you think about our relationship with everyone we work with, we are not just a delivery provider. Many times, we are the growth engine or the growth button, both in terms of what we can bring incrementally from our marketplace as well as the know-how that we bring from our first-party business in teaching these retailers and advertisers on how to build the most successful digital powerhouses in their own rights. And so you see that again here in the Symbiosys example as part of our advertising business.
