当应用程序在前台运行时，Reactnative codepush 不检查更新

如何解决当应用程序在前台运行时，Reactnative codepush 不检查更新

下面的代码工作正常，但预期的情况是当应用程序处于活动状态并在前台运行时，它也假设检查更新并显示对话框，但它仅在应用程序重新启动时检查..

我检查了 official documentations 的 codepush，但这里没有任何问题..为什么当应用程序在前台处于活动状态时它不检查更新？

    if (navigator) {
      setNavigator(navigator);
    }
    SplashScreen.hide();
    syncImmediate();
  },[navigator]);

  const codePushDownloadDidProgress = (progress) => {
