Hi! I see you're having trouble with the FollowMyHealth website. Could you tell me more about what exactly is not working? For example, are you unable to load the website at all, having issues logging in, or experiencing some error messages? Any details will help me guide you better.

Meanwhile, here are some general steps you can try on your iPhone with iOS 18.6.2:

1. Check your internet connection: Make sure you have a stable Wi-Fi or cellular data connection.
2. Clear Safari cache:
- Go to Settings > Safari.
- Tap Clear History and Website Data, then confirm.
3. Try a different browser: If you have another browser app like Chrome or Firefox, see if the website loads there.
4. Restart your iPhone: Sometimes a quick restart clears temporary glitches.
5. Check FollowMyHealth status: Sometimes their service might be down, so visiting a site like Downdetector or checking their social media can help.

If you are trying to log in and can’t, sometimes username or password recovery can work if the account info is not recognized.

Could you let me know which of these you’ve tried or if you see any specific messages? That way, I can help you further with more tailored steps.
