OnLobbyEntered callback returns no metadata?

[YasinAhmet]

I have been using OnLobbyEntered callback to handle joining process. But I have added some custom metadata to send name of the map, as it varies from lobby to lobby. Apparently, it goes like this:

1. Host successfuly sets the metadata // Debug says so

 lobby.SetData("roomName", setRoomName);
lobby.SetData("map", mapName);
lobby.SetData("isDemo", isDemo ? "true" : "false");

2. Matchmaking lists lobbies and can see metadata // I can successfuly render room name, map name etc

Task<Lobby[]> lobbies = SteamMatchmaking.LobbyList.RequestAsync();
yield return new WaitUntil(() => lobbies.IsCompleted);
 if (lobbies.IsFaulted) {
     Debug.LogError("Failed to fetch lobbies: " + lobbies.Exception);
      yield break;
}
Lobby[] fetchedLobbies = lobbies.Result;

3. Player tries to join the lobby and has no metadata // OnLobbyEntered callback => Received lobby reference does not have metadata.

private void OnLobbyEntered(Lobby lobby) {
    lobby.GetData("map"); // No metadata
}

4. Matching with lobby list request workaround // Use RequestAsync metadata instead

Simply some functions that finds a lobby using lobbyId. SteamMatchmaking.LobbyList.RequestAsync()

This works well. But most likely going to break for Friend Only lobbies as it includes matchmaking.

So, any idea what is happening? Am I not supposed to receive metadata through this callback? Looks like we don't have RequestLobbyData, which updates lobby data of a lobby reference. Any healthy workaround?

The issue still persists, Is there any other information I can submit to identify the issue further? The issue pretty much blocked development of my game as I can't transfer session data(map id etc) between players.
