When going onto my leaderboard display frame the game center window opens up, but the default leaderboards shows nothing unless I click on the top left button to go to the leaderboard list and then re-enter my default leaderboard... It should show the proper data from the get go since my default leaderboard has been selected in itunes connect...
Here is how I have it setup :
start of frame > Display default leaderboard
timer is greater than 1 minute > get scores and names from server
Am I missing anything ?
