## Remarks

Lobby properties are only visible to members of the lobby. <br /><br /> If this lobby object is still in the process of asynchronously being created, joined, or claimed via a call to [PFMultiplayerCreateAndJoinLobby()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayercreateandjoinlobby), [PFMultiplayerCreateAndClaimServerLobby](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayercreateandclaimserverlobby), [PFMultiplayerClaimServerLobby()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayerclaimserverlobby) or [PFMultiplayerJoinLobby()](/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayerjoinlobby), this method will return no keys.
