Hi there! I see you’re having an issue related to the client ID on the MyODFW app on your iPhone. To help you better, can you tell me a bit more about what’s happening? For example, are you seeing an error message mentioning the client ID, or is the app not opening or logging in correctly?

In the meantime, a few things we can check since this is on an iPhone:

1. Update the App: Make sure your MyODFW app is updated to the latest version from the App Store. Updates often include fixes for known bugs.

2. Check Network Connection: The app may require a stable cell or Wi-Fi connection, especially during sign-in or client ID verification. Avoid using airplane mode or being completely offline.

3. Restart the App: Try force closing the app and restarting it.

4. Reinstall the App: If the issue persists, try deleting the MyODFW app and reinstalling it. This can often resolve corrupted data or client ID registration issues.

5. Software Update: Confirm your iPhone’s iOS is updated (iOS 15 or later recommended, depending on your device).

If you’ve tried these and still face issues, sometimes the problem relates to the older iPhone models or cached data in the app. Let me know if you want me to walk you through some deeper troubleshooting steps or if there's a particular error showing.

Are you comfortable trying these steps so far?
