@LordOfTheRings On iphone there is an app called Charles, its technically the same app you use on your desktop but for your phone. You can use this tool to listen for inbound and outbound http request from the device without needing to use your computer as a proxy. Here you will be able to view the headers and payloads being passed to Adobe and the responses. You would then want to validate that the values that need to match between Target and Analytics do in fact match. I believe you need to enable SSL and install a certificate for the Charles app to catch the traffic, if you dont do this is will be encrypted and unreadable.
I mentioned using your computer as a proxy, if you dont want to get the app, here is the documentation on how you set that up.
