Hi there! I’m sorry to hear you’re having trouble logging into the Winn-Dixie app—it can be quite frustrating when things don’t work as expected. Since you’re able to log in online, it sounds like this might be an app-specific issue.

Let’s try a few troubleshooting steps to see if we can resolve this:

1. Update the App: Ensure that you have the latest version of the Winn-Dixie app installed. Sometimes, older versions can lead to login issues. Head to the app store on your device and check for any updates.

2. Clear Cache: If you’re using an Android device, try clearing the app cache. You can do this by:
- Going to Settings > Apps.
- Finding and selecting the Winn-Dixie app.
- Tapping on Storage and then selecting Clear Cache.

If you’re on an iPhone, you may need to delete and reinstall the app, as iOS doesn't allow clearing cache directly.

3. Re-enter Your Credentials: After the above steps, open the app again and carefully re-enter your login credentials (email or phone number and password).

4. Check for Account Lockout: Sometimes, after multiple failed login attempts, accounts may temporarily lock for security reasons. If none of the above seem to work, it might be worth waiting a little while before trying again.

5. Contact Support: If you're still having trouble, it’s best to reach out to customer support. You can send an email to [email protected] for further assistance.

Let me know how it goes or if you need additional help with any of the steps! Are you satisfied with the solution I provided?
