The app being developed is developed on iOS and Android. The iOS version created the Facebook app id first, and only asking for email, fb user id, and full name, therefore doesn't need for review.
Then the Android version came along, using the same facebook app, but it incorrectly and unnecessarily asking different (higher) permission for the app, including About Me information and other stuff. That makes the Facebook gives warning that the app need to be submitted for review on the permission page. Now there's a warning on the facebook app dashboard that the app is ineligible for submission because it missing some data it needs.
Currently Ineligible for Submission Your submission is missing data in the following fields: - Privacy Policy URL
Now the Android version has already refined so it asks the same permission as the iOS version, but the warning won't go away. How can I make it go away without providing privacy policy URL? (provided that it was working without issue before the Android integration came along)
After meddling around, I finally found the way. Just go to App Review menu in the Dashboard, on the Current Submission section, click on "Start Over".
