Based on the provided knowledge sources, there isn't enough specific information to fully answer how to define UTM sources in app download links. However, I can provide some relevant context about UTM tracking and mobile attribution in Mixpanel: For mobile apps, tracking campaign sources (including UTM parameters) for app installs is more complex than on the web due to how mobile devices handle attribution information Mobile Attribution.For Android, Google provides a Play Install Referrer Library that allows retrieving referrer information for app installs. You could potentially use this to capture UTM parameters, but the exact implementation isn't detailed in the provided sources.For iOS, the situation is more challenging. The Apple App Store strips attribution data when users enter it, so users who download your app don't carry information about where they came from before reaching the App Store.To track channel attribution on iOS, including UTM sources, Mixpanel recommends using a mobile attribution tool. Mixpanel integrates with various mobile attribution partners, which you can find on their tech partners page.Unfortunately, the knowledge sources don't provide specific instructions on how to define UTM sources in app download links. For more detailed guidance, you may need to consult Mixpanel's documentation on mobile attribution or reach out to their support team.
