I'm reading Apple's documentation for "Turning On Game Center for the App Version" and at the end of section "To enable a version of your app for Game Center" step 7 says:
"Submit for Review"
My app is unpublished and still in development, so I'm reluctant to submit for review. On the other hand my API calls to report/load scores are failing.
Is it required to submit for review in order to test the leaderboard APIs?
What happens after submitting for review? Can I delete the leaderboard later on?
