Flutter Web项目无法在Firebase Analytics查看历史活动数据

我开发的Flutter Web游戏项目已集成Firebase Analytics，能看到过去30分钟的实时用户数据，但完全看不到任何历史用户或事件数据。昨天刚给项目添加Firebase时就有不少用户访问，但今天查不到这些事件记录。

我反复检查过设置流程，确认配置没有问题。

今早访问网站时，实时记录里能看到自己的访问数据：

但历史用户活动时间线图表完全没有数据：

单例Analytics类代码 #

// Singleton class to hold the Analytics for for Firebase
import 'package:firebase_analytics/firebase_analytics.dart';
import 'package:firebase_core/firebase_core.dart';
import 'package:septuple/firebase_options.dart';

class Analytics {
  Analytics._();

  // Generate an instance of the firebase analytics class
  final FirebaseAnalytics analytics = FirebaseAnalytics.instance;

  // Create an instance of this class as a singleton
  static final Analytics _instance = Analytics._();

  // Initialise firebase for the app
  static Future<void> init() async {
    await Firebase.initializeApp(
      options: DefaultFirebaseOptions.currentPlatform,
    );
    getData().setAnalyticsCollectionEnabled(true);
  }

  //Get the FirebaseAnalystics object to do event logging
  static FirebaseAnalytics getData() {
    return _instance.analytics;
  }
}

main方法初始化代码 #

void main() async {
  //
  // Initialise the Hive database
  await Hive.initFlutter();
  await Hive.openBox('septupleBox');
  //
  // Initialise firebase in the Analytics singleton to enable event logging
  //
  await Analytics.init();
  //
  // Run the app
  runApp(Game());
}

事件记录代码（以用户猜对单词为例） #

void setWin(int attempts) {
    // Log end of game and that the user guessed correctly
    Analytics.getData().logLevelEnd(
      levelName: 'septuple',
      success: attempts,
    );
    gameState = GameState.win;
    _box.put(_gameStateName, gameState.toString());
    _game.gameTimer.startCountdown();
    notifyListeners();
  }

logLevelEnd是默认事件类型，我以为它会直接显示在Firebase Analytics中，是不是需要额外配置才能捕获并保留该事件？

另外我已经参考相关帖子等待了26小时（从看到实时数据开始算），但历史数据还是为空。

请问为什么Firebase Analytics里看不到历史用户或事件数据？
