Enhancing Your Shopping: Discovering GU App Advantages

Unexpected App Behavior: Getting Back to Seamless Shopping

⚠️ Unable to Log In

Cause: Incorrect email or password, or an existing account conflict.

Solution: We understand being locked out can be frustrating. First, double-check your email address and password for any typos. Ensure you're not accidentally copying extra spaces if pasting your credentials. If you've previously registered with UNIQLO, remember that your login details are shared between GU and UNIQLO. If you continue to face issues, utilize the パスワード設定・再設定について (About password setting/re-setting) option on the login screen to reset your password. If your email is reported as 'already registered,' it might be connected to a UNIQLO account already.

⚠️ App Not Functioning Correctly or Showing Errors

Cause: Outdated app version, network issues, or device incompatibility.

Solution: Unexpected app behavior can often be resolved with a few simple steps. Ensure your GU App is updated to the latest version via your device's app store (App Store for iPhone, Google Play Store for Android). Verify that your device has a stable network connection. If you're experiencing errors, especially during payment processes like PayPay, ensure your device's operating system (iOS 16.0+ or Android 9.0+) is supported, and try accessing the online store via Google Chrome if the issue persists on the app.

⚠️ Purchase History Not Displaying Correctly

Cause: Logged in with a different account than the one used for the purchase.

Solution: If your purchase history appears incomplete, it's likely you are logged into a different account than the one used for your previous transactions. Simply log out of the current account and then log back in using the correct email and password associated with those purchases. This will refresh your personalized history.

Q: How can I check product availability at a specific GU store using the app?

The GU App allows you to easily check the stock status of products at any physical store. Simply search for the item you're interested in, and the app will display its availability at nearby or selected GU locations, helping you plan your in-store visit efficiently.
