This issue is still persisting in 2021.3 LTS.

All users show as unknown.

the issue is present in Unity 2020.3.21f1

userName returns as "Unknown"

the issue is present in Unity 2019.4.31f

And how do I get names now with Social.Active.LoadUsers? LoadUsers requires the old ID and IScore contains the new one. This is such nonsense.

version Version '2020.3.3f1 (76626098c1c4)' works for me so the fix in Fixed in 2020.3.6f1 probably ruined something

Im having the same issue on engine version: 2020.3.11f1 (99c7afb366b3)

I'm using Unity 2020.3.12f1 and am unable to get the correct ID to pass into Social.Active.LoadUsers

I tried to fetch scores from a friend leader board with the scope set to this week only and I'm still getting three different IDs and their username is just "Unknown" with friendFlag set to "false".

When I log out the friends ID at each step of the process they are all different.

Friend ID returned from Social.localUser.LoadFriends - 162451708288547808
Friend ID returned from localLeaderboard.LoadScores - 162451708373532384
Friend ID returned in the profiles from Social.Active.LoadUsers - 162451708425354208

The issue continues.

Unity Editor Version : 2019.4.28f1

Code :

ILeaderboard mLeaderBoard = Social.CreateLeaderboard();
mLeaderBoard.id = "leaderboardID";
mLeaderBoard.userScope = UserScope.Global;
mLeaderBoard.timeScope = TimeScope.AllTime;
mLeaderBoard.range = new Range(1, 30);

mLeaderBoard.LoadScores(result =>
{
if (result)
{
Debug.Log("Scores Length : " + mLeaderBoard.scores.Length); //Output : "Scores Length : 30"

List<string> userIDs = new List<string>();

for (int i = 0; i < mLeaderBoard.scores.Length; i++)
userIDs.Add(mLeaderBoard.scores[i].userID);

Debug.Log("UserIDs Count : " + userIDs.Count); //Output : "UserIDs Count : 30"
Debug.Log("UserID[0] : " + userIDs[0]); //Output : "UserID[0] : 162334654......"
Debug.Log("Player ID : " + Social.localUser.id); //Output : "Player ID : T:_9953b2d1m32......"

Social.LoadUsers(userIDs.ToArray(), (users) =>
{
Debug.Log("Users Length : " + users.Length); //Output : "Users Length : 0"
});
}
});

Although 30 Scores are returned, users information is not loaded. Social.LoadUsers function returns user array of length is 0.
It also gives the following error in XCode Console :

"GKPlayer: _loadPlayersForIdentifiers: - Failed to get profiles for Player IDs due to error: Error Domain=GKErrorDomain Code=8 "The requested operation could not be completed because the player is invalid." UserInfo={GKServerStatusCode=5005, NSLocalizedDescription=The requested operation could not be completed because the player is invalid., NSUnderlyingError=0x600000e11d70 {Error Domain=GKServerErrorDomain Code=5005 "status = 5005, NO SUCH PLAYER ID" UserInfo={GKServerStatusCode=5005, NSLocalizedFailureReason=status = 5005, NO SUCH PLAYER ID}}} "

I noticed here that the userID of the users on the leaderboard are not similar to Social.localuser.id. Different types. So I tried using Social.LoadUsers function with Social.localuser.id

Code:

List<string> userIDs = new List<string>();
userIDs.Add(Social.localUser.id);
Social.LoadUsers(userIDs.ToArray(), (users) =>
{
Debug.Log("Users Length : " + users.Length); //Output : "Users Length : 0"
});

But the result is the same. Social.LoadUsers function returns 0. But this time it didn't give any error in XCode Console.
