You're working with a clothing distributor that's launching a new line of scarves. They're running ads across mobile web and in-app inventory. If they want to see purchases across both platforms, which report should you run?

The Instant Report with the total conversions metric is the most direct way to see purchases across both mobile web and in-app platforms. This report provides immediate, aggregated data on all conversions, including purchases, regardless of the platform they occurred on. The Path to Conversion Report focuses on the sequence of interactions leading to a conversion, not just the total count, and while revenue is important, the question specifically asks for purchases (conversions). The Reach Report measures how many unique users saw the ads, not conversions. The Multi-device Report is designed to show conversions across different devices (e.g., phone, tablet, desktop), not specifically differentiating between mobile web and in-app on the same device type, and Campaign Manager 360's standard conversion tracking already handles cross-platform conversions within the Instant Report.
