Yesterday at about 10am Apple sent me the approval email. I got it around 12pm and immediately logged into iTunes Connect and set the release date it to February 9 (it was set to much later in February). After about an hour I could find it in the App Store, but I kept checking recent releases in Adventure and Arcade games, but it wasn't there. And today, about 24 hours later, it's still not listed. Any ideas?
Ground Effect Lite was released around 18:00 GMT on February 8. It didn't show on the new release list until some time after 02:00 but before 07:30 GMT on february 10. I think the time to get worried is when apps with a later date than your release show up first.
