Hi, I have a free game on app store, now I want to submit a paid version of this game. Since I want to them to share the same Leaderboards and Achievements in game center, I move them into one "game center group"..
Now does it mean I should change all those Leaderboards and Achievements IDs to include the prefix "grp." for both Free and Paid version??
Thanks!!
