For anyone coming here doing Unity stuff, @krince advice worked for me. Deleted my local provisioning profiles and after that my build was correctly recognized as having the GC entitlements: I forced a re-creation of the automatically managed provision profiles (deleted everything under ~/Library/MobileDevice/Provisioning\ Profiles)

Same issue here. One thing I noticed is that in the list of entitlements, when I submit a build via xCode to the App Store, the Game Center one is actually missing, even though it's activated in in xCode. Can anyone see the GC entitlement when they upload?
