During development I\'ve created test accounts which are able to obtain the price of the in app purchase as well as actually purchasing it without an issue. However after pu
I didn't have to wait long, something like a couple hours and it just started working.
Now, my binary and my In-App Purhcase were approved at the same time and almost immediately after they were both approved, I released the app version to the store.
I'm not positive, but what I probably should have done was wait a couple hours before releasing that new app version and give the In-App Purchase a chance to "register" or "propagate" in the Production App Store.
Just a recommendation for others.
