As of the past few days [GKLeaderboard loadScoresWithCompletionHandler: ^(NSArray *scores,NSError *error)] for GKLeaderboardPlayerScopeGlobal is returning anonymous scores instead of actual names.
Sample:
player:playerID:AnonymousID alias:Anonymous rank:24 date:2017-10-25 03:16:58 +0000 value:65414600 formattedValue:65,414,600 points context:0x0 leaderboard:someLeaderboard group:(null)

Anybody else seeing this? It's affecting every one of my games.
