To understand our issue, you have to know our postback journey. 1. We are using ADJUST MMP to collect the user data from our mobile app. 2. We're using SALES campaign and using WEB to APP model. User download app by clicking download button on website. 3. We also installed the pixel on our landing page so on Event manager, Page view will be shown BROWSER. 4. For other events such as complete registration, purchase, It will be shown as Coversion API. We integrated this event with ADJUST MMP
So refer to our screenshot, SERVER sending client IP address with multiple users issue.
