Hi there! I understand you’re encountering error 4100 every time you try to edit your email address on the Regions app. Let’s get that sorted out.

To make sure I help you the best way possible, can you tell me a bit more? For example:
- Are you trying to update the email address linked to your Regions bank account or related to Zelle within the Regions app?
- Have you noticed if the app gives any additional message along with the error 4100?
- Have you tried editing the email address from another device or via the Regions website?

Error 4100 is often linked to verification or account linkage issues within the app. Here are some steps you can try to resolve it:

1. Confirm Account Verification: Make sure your Regions account and Zelle (if linked) are fully verified with accurate information. Sometimes, the app can’t update if it detects mismatched or invalid account IDs.

2. Update the App: Go to your iPhone’s App Store and check if there is an update available for the Regions app. Running the latest version helps avoid bugs that cause errors.

3. Restart the App and Device: Close the Regions app completely (swipe up on the app in the app switcher), then power off your iPhone and restart it. Then try editing the email again.

4. Clear the App Cache/Data:
- iOS apps don’t have a direct “clear cache” option, but you can uninstall the Regions app and reinstall it from the App Store. This often clears residual data that might be causing errors.

5. Check Network Connection: Make sure you have a stable internet connection—either Wi-Fi or cellular data. Sometimes network issues cause errors during updates.

6. Try Editing via Browser: Log in to your Regions online banking through Safari on your iPhone and attempt to update your email address from there. This can help isolate whether the problem is app-specific.

7. Zelle-specific Issues: If you use Zelle through the Regions app, the 4100 error can indicate an issue with Zelle account verification. Verifying your identity and linked phone/email in Zelle settings may help. You can check Regions’ Zelle support page for more on managing your account.

If you’ve tried these and still see error 4100, the problem might be deeper in the system recognizing your account ID or linked devices, which is typically identified by the Regions backend system.

Would you like me to guide you through any of these steps? Or if you already tried some, please let me know what you’ve done so we can move to more advanced troubleshooting.

Are you hoping to update your email for your bank contact info, Zelle, or both? That detail will also help me assist better.

The email I’m trying to change is the one on my regions account not zell .will lockdown mode on the phone cause this problem

Thanks for clarifying that you’re updating the email address linked directly to your Regions account, not Zelle. That helps narrow things down! As for your question about Lockdown Mode on your iPhone, it’s a security feature that restricts certain network and app behaviors to protect your device. It could potentially interfere with app functions that require communication with Regions servers, like updating account info, though it’s not a frequent cause of error 4100 specifically.

Here’s what I recommend:

1. Temporarily Disable Lockdown Mode: Since you have it enabled, try turning Lockdown Mode off temporarily:
- Go to Settings > Privacy & Security > Lockdown Mode
- Toggle Lockdown Mode off and restart your iPhone.
- Then try updating your email address again in the Regions app.

This will check if Lockdown Mode is blocking any needed connections.

2. Follow Proper Steps to Change Email on Regions App:
- Open the Regions app on your iPhone and log in.
- Tap the Profile & Settings icon.
- Select "Contact information."
- Choose the email address and tap “Edit.”
- Enter your new email and save the changes.

This is the supported way to update your email on the app1 2.

3. Check for any App or iOS Updates: While you’re at it, verify your Regions app and your iPhone iOS version are current to avoid bugs.

4. Use Web Banking if Needed: If the app still returns error 4100 after disabling Lockdown Mode, try updating your email by logging into Regions Online Banking via Safari on your iPhone:
- Once logged in, go to Customer Service > Settings > Contact & Security Info > Email.
- Edit and save your new email address there.

If this still doesn’t resolve the error 4100, it may relate to backend account matching or security checks on the Regions side, and I’d recommend contacting Regions support directly by emailing [email protected] for deeper assistance.

Would you like help stepping through turning off Lockdown Mode or through updating your email on the app? Let me know! Are you satisfied with this solution so far?
