I was testing out an update to my app, and while logged into my gamecenter sandbox account on the device, ran my project on my iPhone. Foolishly, without thinking to check I was in sandbox mode, I ran the game with a cheat I enabled for testing purposes to skip to the end. Consequently, my sandbox account now has the highest score on the live GC leaderboards!
I was hoping there might be some backdoor way to delete my own score. Anyone have any advice?
If I understand your question correctly, what you can do is log into your iTunesConnect account, go to “Manage Your Applications” select your game, select “manage game center”, then click on “Delete Test Data”.
