If you are experiencing issues with adding or verifying a card in the My H-E-B app, follow these steps to identify and resolve the problem:

1. Check Internet Connection
Ensure your device is connected to a stable internet connection. A weak or unsteady connection may prevent the app from processing payment information.

2. Update the App
Make sure that you have the latest version of the My H-E-B app. Check the App Store for any available updates and install them.

3. Restart the App
Close the app completely and then restart it. This can refresh its connection and may resolve temporary glitches.

4. Enter Card Details Correctly
Double-check the details you are entering for the card, including the card number, expiration date, CVV code, and billing address. Any incorrect information might lead to an error when verifying the card.

5. Use a Different Card
If possible, try adding a different credit or debit card. Some users have reported success by using another card if the app rejects the first one - learn more.

6. Clear App Cache
If you're on an iOS device, clearing the app’s cache may help. This can be done by going into your device settings, finding the app, and selecting the option to clear cache or storage.

7. Contact Customer Service
