Hi there! I understand you're having trouble with the verification code saying it's invalid when signing back into the Save Mart Supermarkets app. Let's work through this together.

To start, can you tell me if you're receiving the code via SMS, email, or an authenticator app? Also, have you checked that the code you're entering exactly matches what's sent (watching for spaces or characters)? Sometimes these small details matter.

Here are some step-by-step things to try:

1. Check the Time on Your Device: If you're using an authenticator app, make sure your device's clock is set correctly. Time mismatch can cause codes to appear invalid.

2. Request a New Code: Sometimes codes can expire quickly. Try resending the verification code and enter it as soon as you receive it.

3. Clear Cache or Restart the App: Close the Save Mart app completely, restart your device, then open the app and try again.

4. Try a Different Network: If possible, switch from Wi-Fi to mobile data (or vice versa) when receiving the code, as network issues can interfere with code delivery.

5. Confirm Contact Information: Double-check that the phone number or email registered for your account is correct and accessible.

If you've tried these and it still doesn't work, it might be an issue with the app or your account settings. Let me know what you've already attempted, and I can help dive deeper or guide you on contacting Save Mart support if needed.

Are you currently using an authenticator app for this, or getting codes via SMS/email?
