I can update a score to Game Centre with 3 different sandbox accounts on 3 different iOS devices, using Corona’s gameNetwork.request() API. However, each device can see only the local score (shown as “Me”).
Scores by other devices can only be updated if all the players (i.e. all sandbox accounts) are friends of each other. In this case the scores of each other were updated immediately on screen of every devices.
I guess there may be a long delay for data update in Sandbox environment. To my surprise, after about 15~20 hours all the scores are removed from the Game Center. Within the Game Center UI all players are displayed as “No Scores”.
Besides, all achievements records are clocked in the severs, even the leaderboard scores were gone.
I just wonder if this is normal for Game Centre Sandbox testing? Did I do something wrong in ituneConnect setting? I am worry about is it a problem of Corona’s API? Will everything becomes normal out of the Sandbox environment when the App is published?
Please help.
