## Remarks

This is an asynchronous operation. Upon successful completion, the title is provided a [PlayFabMultiplayer.PlayFabMultiplayerServer.OnServerPostUpdateAsServerCompleted](https://docs.xbox.com/services/playfab/multiplayer/lobby/unity-multiplayer-api-reference/PlayFab.Multiplayer/PlayFabMultiplayer.PlayFabMultiplayerServer/overview.md) with the `OnServerPostUpdateAsServerCompleted result` field set to [Success](https://docs.xbox.com/services/playfab/multiplayer/lobby/unity-multiplayer-api-reference/PlayFab.Multiplayer/LobbyError/Success.md). Upon a failed completion, the title is provided a [PlayFabMultiplayer.PlayFabMultiplayerServer.OnServerPostUpdateAsServerCompleted](https://docs.xbox.com/services/playfab/multiplayer/lobby/unity-multiplayer-api-reference/PlayFab.Multiplayer/PlayFabMultiplayer.PlayFabMultiplayerServer/overview.md) with the `OnServerPostUpdateAsServerCompleted result` field set to a failed error code. If applying the update would change the state of the lobby, the title is provided a [OnLobbyUpdated](https://docs.xbox.com/services/playfab/multiplayer/lobby/unity-multiplayer-api-reference/PlayFab.Multiplayer/PlayFabMultiplayer/OnLobbyUpdated.md) sometime afterwards.

This operation completing successfully only indicates that the Lobby service accepted the update. The title's local view of the lobby state doesn't reflect this update until a [OnLobbyUpdated](https://docs.xbox.com/services/playfab/multiplayer/lobby/unity-multiplayer-api-reference/PlayFab.Multiplayer/PlayFabMultiplayer/OnLobbyUpdated.md) is provided to the title with the updated state.

This operation is restricted to client-owned lobbies that are using connections.

While this method is present in the unified, cross-platform header, it only implemented for Windows and, XBOX. The method returns errors on other platforms.
