I've had this problem for a couple weeks now, and I can't seem to find the fix.
I'm using Unity 5.5.1. The app I've created contains ads and IAP, but neither work whenever I upload the game to the App Store, and download it from there. (After Apple reviews it and I publish it)
To my surprise, however, the ads work whenever I upload the game to the iPhone directly, through Xcode. (The fact that IAP doesn't is common)
Below are my Xcode settings. I do not get any errors throughout the uploading and review processes, so I am completely lost right now.
PS. Similar build works perfectly on Play Store.
