Game Center UI failing to load in app

Unity Engine

I’ve implemented Game Center functionality using the Unity Social API - everything seems to be working nicely except for one thing, when calling Social.ShowAchievementsUI() and ShowLeaderboardUI from within the app, the UI fails to load. It looks like it’s waiting for the icon images to load - but it just sits there indefinitely on the spinning loading icon. Doesn’t seem to time out, either, just sits there.

It loads fine from the Game Center app.

Any ideas?

Update:

Tested a few hours later on iPad running iOS 6.1 - GC UI loaded fine

Tested again on iPhone running iOS 6.0 - GC UI failed to load

Updated iPhone to iOS 6.1 - GC UI loaded fine
