Game Center - timeScope not working?

I am using the gameNetwork.show() command to display the leaderboards for my app.  I provide it the timeScope parameter in order to specify whether they should be shown by “Today”/“Week”/“AllTime”.   However, it seems that no matter what I choose, the display always shows All-Time leaderboard results in IOS 7 Game Center.  

I am using a sandbox account for this case (since this update has not been submitted yet to Apple), and am wondering whether this only occurs for sandbox?  

e.g.  I selected “Today”, but scores from previous days show up.

My code:

gameNetwork.show("leaderboards", { leaderboard = {category = my\_selected\_category, timeScope = selected\_scope} })
  • where ‘selected_scope’ is one of:  “Today”, “Week” or “AllTime”

i am facing the same issues, but still waiting for a reply (a few weeks ago).

Same issue happens if I use gameNetwork.request() instead to grab the values.

Oh… I just noticed your post in the Game Networking forum.  Looks like these sub-forums are not monitored as much as the other ones?
