I found a problem with ListGameFriendsRequest. After user has registered to the game by Facebook Connect, I want to give his/her Facebook friends an extra virtual good. I noticed that I don't have that player in my list after it joined, he appeared on the list when I did the request after a couple minutes. Probably there's a cache or delay in GameSparks for it.
Is there any way to make it faster or should I check that f.e. every five minutes?
This is being handled in your ticket.
