After creating and testing my first IAP in iTunesConnect, I created a new app version and connected it to the IAP (as you must with it being the first one).
The binary for the app version I submitted was rejected, so I corrected the issue and went to resubmit however I do not see the IAP section appearing in the app version details. I have sections for version information, meatadata and uploads, app review information, and EULA, but not for in-app purchase. Is there something I'm missing? Does an IAP need to be "reattached" to a version after a rejection to the binary (not the IAP), or does the IAP remain connected to the version and simply get reviewed with the resubmitted binary? It's confusing that it is not listed on the Version Details page at all, which is why I wanted to reach out for some help before waiting through the entire review process...
Thanks for the help!
