Per-member properties are only visible to members of the lobby and the server if this is a server-owned lobby. \
\
 If the member is still in the process of asynchronously joining this lobby either via [PFMultiplayerCreateAndJoinLobby()](https://docs.xbox.com/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayercreateandjoinlobby.md), [PFMultiplayerJoinLobby()](https://docs.xbox.com/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayerjoinlobby.md), or [PFLobbyAddMember](https://docs.xbox.com/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pflobbyaddmember.md), this method will return no keys.
