The app refreshes about every four seconds. Since this app has been updated it's utterly useless. All it does is refresh, sometimes even before the initial app is completely loaded. I'm never able to shop, let alone search, for items because it constantly refreshes. I have uninstalled this app and reinstalled it several times but it makes no difference. It continues to exhibit the same behavior the entire time the app is open. First time Costco has disappointed.
