Ios app rejected due to third-party advertising, analytics or IDFA

Hello

I’ve been having a problem submitting an app for apple review, however i am getting rejected due to third party analytics, advertising or some kind of information shared with others. I have disabled all mobile or network related plugins, also unchecked the IDFA setting in project settings. Even with all this I am still getting rejected. Is there some tool to check what in my code is going against apple’s guidelines? Am I missing some setting in the building process?

Note: this app was previously packaged to the apple store without problems using ue 4.25.2, also this app doesn’t use network capabilities or analytics.

Thanks

We are having this EXACT problem. Apple insists we need to remove the IFDA from our binary - how? Wonder why Apple wouldn’t flag it at any stage of the TestFlight process? And they are being totally unhelpful, but it looks like we need help from the UT team.
