If I were faced with this situation, my first step would be to gather more data to understand why introducing Ads inside the dating product resulted in decreased engagement. I would want to know which specific ads were shown, where they were placed within the product, and how often they were displayed to users. I would also want to understand the demographics of the users who saw the ads and those who did not. Once I had a better understanding of the data, I would want to explore alternative options for monetizing the product that would not negatively impact user engagement. This could include partnerships with relevant brands or businesses, offering premium features for a fee, or finding other creative ways to generate revenue. In the end, my goal as a product manager would be to find a way to monetize the product while still providing value to users and maintaining a positive user experience. It might require some trial and error, but I would be committed to finding a solution that works for everyone involved.
