Why is this URL in my Bing Ads reporting?

Bing Ads reports on clicks from search partners by URL, but mobile applications do not have URLs.

When Bing advertisers receive clicks from searches within a mobile app, Bing Ads reports a URL to a webpage where you can learn about the mobile app where the search occurred.

In this case, clicks came from users who searched on the cPro Craigslist Mobile Client mobile app, through Bing's partnership with adMarketplace.

Here is a screenshot of the app with a sample ad placement.
