Hi there! I’m sorry to hear you're having trouble logging into the Merrick Bank mobile app with that message about your information not matching records. Let's see if we can get this sorted out.

To start, could you tell me if you are entering your username, password, card number, or any other specific information? Also, have you recently updated or changed any personal details like your name, address, or phone number with Merrick Bank?

Here’s a step-by-step approach we can try together:

1. Double-check the details you're entering: Make sure your username and password are exactly as you created them, paying attention to capitalization and special characters.

2. If your login requires your card number or social security number, ensure you are typing the correct numbers without extra spaces or dashes.

3. Try resetting your password using the "Forgot Password" link on the app login screen to ensure you have the latest login credentials.

4. If you’ve changed your personal details recently, it might take some time for the system to update. Sometimes logging in right after an update can cause mismatch errors.

5. Make sure your app is updated to the latest version from your app store, as older versions may have issues connecting properly.

If you've tried these and still see the error, it might be necessary to verify your account details in our system. Would you like me to guide you through contacting Merrick Bank’s support team for further verification?

Let me know what you’ve tried so far and we can get you back into your account!
