Hi there! I see you're having trouble registering in the Lifeway On Demand app on your iPhone with iOS 18.6. I'd love to help you get that sorted out.

First, could you tell me a bit more about what's happening when you try to register? For example:
- Do you get any error messages?
- Does the app freeze or just not respond?
- Have you already created an account on Lifeway's website or tried registering directly within the app?

Getting these details will help me guide you more precisely. Meanwhile, here are some initial steps we can try:

1. Check Internet Connection: Ensure you have a stable internet connection, either Wi-Fi or cellular data.

2. Update the App: Make sure your Lifeway On Demand app is updated to the latest version from the App Store. Updates often fix registration bugs.

3. Restart the App and Device: Close the app completely (swipe it away from recent apps) and restart your iPhone to clear any temporary glitches.

4. Try Registering on the Website: Visit my.lifeway.com on your iPhone’s browser and attempt to register there. Sometimes registration works better through the website and then you can log in via the app.

5. Check Age and Terms: Make sure you are certifying that you are at least 13 years old and agree to the terms and conditions, as this can block registration if not confirmed.

If you’ve already tried these or still face issues, let me know the error or behavior details you see, and I can assist with more advanced troubleshooting steps!

Are you able to share what step you reached or any messages displayed during registration?
