Facebook图谱排行榜不会立即更新。

我正在创建一个 Facebook 排行榜，但在更新时遇到了一些问题。当我更新 Facebook 得分，然后打开排行榜时，它显示的是老分数。如果我关闭游戏并再次打开游戏，它显示正确的排行榜。我做错了什么？

这里是代码：

function fClassificaFb(event)
if event.phase == "began" then
    bpClassificaFb.isVisible = true
end
if event.phase == "moved" then
    bpClassificaFb.isVisible = false
end
if event.phase == "ended" then
    bpClassificaFb.isVisible = false
    fbAggiornaClassifica()
    timer.performWithDelay(150, fbVisualizzaClassifica, 1)
end
end

function fbVisualizzaClassifica(event)
    local status = network.getConnectionStatus()
    if status.isConnected then
        facebook.login(appID, fbListener)
    else
        fbAlert = native.showAlert("Errore di connessione", "Non è stata rilevata alcuna connessione a Internet.", {"Annulla", "Riprova"}, fbReLogin)
    end
end

function fbAggiornaClassifica()
    local status = network.getConnectionStatus()
    if status.isConnected then
        facebook.login(appID, fbListenerAggiorna)
    else
        fbAlertAggiorna = native.showAlert("Errore di connessione", "Non è stata rilevata alcuna connessione a Internet.", {"Annulla", "Riprova"}, fbReLoginAggiorna)
    end
end

function fbListener(event)
    if "session" == event.type then
        if "login" == event.phase then
            access_token = event.token
            facebook.request(appID.."/scores")
        end
    elseif "request" == event.type then
        local response = json.decode(event.response)
        myData.dataFriends = response.data
        storyboard.gotoScene("classifica_facebook")
    end
end

function fbListenerAggiorna(event)
    if "session" == event.type then
        if "login" == event.phase then
            access_token  = event.token
                if storyboard.state.punteggio > myTable.highScore then
                    myTable.highScore = storyboard.state.punteggio
                end
                loadsave.saveTable(myTable, "myTable.json")
                local attachment = {
                    score = tostring(myTable.highScore)
                }
                facebook.request("me/scores" , "POST", attachment)
        elseif "request" == event.type then
        end
    end
end
