Not finding any lobbies through the REST API

I'm trying to use the REST API in Unity to create and find lobbies, but even though I can successfully create a lobby and connect to it as the owner, every call to FindLobbies returns zero results.

The API requests do include the X-EntityToken header, and I don't see any errors, so I'm not sure what I might be doing wrong.


(I'm not currently using the Unity Lobbies SDK for this because that doesn't seem to work on Android.)

I have a public repo here in case more context is useful, but below is the function that attempts to find the lobbies:

public static bool FindLobbies(string search, 
    Action<List<LobbySummary>> onSuccessCallback, 
    Action<string> onErrorCallback
){
    if (PlayerEntity.LocalPlayer != null){
        OnScreenMessage.SetText("Finding Lobbies...");
        var requestProps = new FindLobbiesRequest {};
        PlayFabMultiplayerAPI.FindLobbies(
            requestProps,
            r => APIOnLobbyFindLobbiesCompleted(r, onSuccessCallback),
            e => Debug.LogError(e.GenerateErrorReport())
        );
        return true;
    }
    return false;
}


private static void APIOnLobbyFindLobbiesCompleted(
    FindLobbiesResult result, 
    Action<List<LobbySummary>> callback
){
    ExtDebug.LogJson("APIOnLobbyFindLobbiesCompleted", result);
    callback?.Invoke(result.Lobbies);
}

And this is the function that creates the lobby:

public static void CreateAndJoinLobby(
    string name,
    string level,
    uint maxPlayers,
    bool isInvisible,
    bool isPublic,
    Action<PlayFab.MultiplayerModels.Lobby> successCallback,
    Action<string> errorCallback
){
    OnScreenMessage.SetText($"Creating lobby: {name}...");
    PlayFabMultiplayerAPI.CreateLobby(
        new CreateLobbyRequest {
            MaxPlayers = maxPlayers,
            OwnerMigrationPolicy = OwnerMigrationPolicy.Automatic,
            AccessPolicy = isPublic ? AccessPolicy.Public : AccessPolicy.Private,
            SearchData = new Dictionary<string, string>{
                {LobbyWrapper.LOBBY_NAME_SEARCH_KEY, name},
                {LobbyWrapper.LOBBY_LEVEL_SEARCH_KEY, level},
                {LobbyWrapper.LOBBY_VISIBILITY_SEARCH_KEY, (
                    isInvisible ? ((int)LobbyWrapper.LobbyVisibility.Invisible) 
                    : ((int)LobbyWrapper.LobbyVisibility.Visible)
                ).ToString()},
            },
            LobbyData = new Dictionary<string, string>{
                {LobbyWrapper.LOBBY_NAME_KEY, name},
                {LobbyWrapper.LOBBY_LEVEL_KEY, level},
                {LobbyWrapper.LOBBY_SESSION_KEY, Guid.NewGuid().ToString()},
            },
            Owner = PlayerEntity.LocalPlayer.entityKey,
            UseConnections = true,
            Members = new List<Member>{
                new Member {
                    MemberData = new Dictionary<string, string>{
                        {PlayerEntity.PLAYER_NAME_KEY, PlayerEntity.LocalPlayer.name}
                    },
                    MemberEntity = PlayerEntity.LocalPlayer.entityKey,
                }
            }
        },
        r => _OnLobbyCreated(r, successCallback, errorCallback),
        e => OnError(e, errorCallback)
    );
}

I just noticed that the FindLobbies function works if the lobby was created using the Lobbies SDK instead of the REST API. I think I'll do some more debugging to see if I can figure out what the difference is.

The Lobby needs a connected entity to be searchable. Since the REST APIs are stateless, you can only search lobbies which created by Lobby SDKs, as they can keep connection with Lobby service.
