It’s all working fine in Sandbox mode, however I’m unsure if I have to do anything special before I submit it to apple, so it doesn’t use sandbox mode? I can’t seem to find any info on it. :roll:
Hi, here’s what I did in my recent release with GameCenter support.
When add a new version to the app, like antony said, click the Enable GameCenter button (which is below the screenshot section), then you can choose and add the leaderboards and achievements that you have created before into this version.
