We’re only aware of a Facebook-related issue. If that’s your issue, you can go to this thread:
I receive the same message when uploading: Improper Advertising Identifier [IDFA] Usage. Your app contains the Advertising Identifier [IDFA] API but you have not indicated its usage on the Prepare for Upload page in iTunes Connect.
Is there a build-setting to prevent this?

I updated to Corona Pro and this issue was resolved.
Thanx for the continious support!
