I have an iOS game with one Game Center leaderboard. Recently I published the game and it works fine with no issues. Then I did light version of the game and I'd like to use the same leaderboard for both games. I combined both versions of the game into the Game Center Group and modified leaderboard ID, because Apple requires to start group leaderboard names with "grp.".Now, if I load scores I receive nil. But if I firstly submit some score and load after that I receive only score for the local player. I checked the leaderboard on itunesconnect and I know for sure that there are a lot of records in the leaderboard. The leaderboard is the same as it was before combining into the group. I thought that Game Center needs some time to update, but I've waited about several days and still see no changing.Do I do something wrong? Or this is just a Game Center bug?I found some similar issues here but with no reply. Does anyone has any ideas? Any help appreciated!
