Facing Hurdles? Resolving CAINZ App Access and Performance Issues

⚠️ Unable to Log In or App is Stuck Loading

Cause: Incorrect credentials, temporary registration status, or app data issues.

Solution: We know being locked out is stressful. First, double-check your entered password and email address for any typos. If you suspect an incorrect password, use the パスワードの再設定 (password reset) option. If the app remains stuck loading, try clearing past data from your device's settings. Also, ensure you've completed full member registration, as temporary registration (e.g., scanning only a CAINZ card barcode) might restrict full login access; full registration is needed for your points to display properly.

⚠️ Membership Card Barcode Not Displaying

Cause: App interface error or temporary glitch.

Solution: If your barcode isn't showing, tap the 会員証 (Membership Card) icon located at the bottom right of the home screen. If the issue persists due to an app error, restarting your device and ensuring the app is updated to the latest version can often resolve it.

⚠️ Authentication Code Not Received

Cause: Email filtering or incorrect email address.

Solution: When an authentication code doesn't arrive, first check your spam or junk mail folder. Confirm that the email address associated with your account is correct and free of errors.

⚠️ App Crashing Frequently

Cause: Compatibility issues or software glitches.

Solution: For frequent app crashes, verify that your device meets the recommended operating system requirements. A simple device restart and updating the CAINZ app to its newest version can often improve stability.
