Hi there! I see you're having trouble logging into the Goodnight app on your iPhone with iOS 18.6.2. I’d love to help you get this sorted.

To start, could you tell me if you’re seeing any error messages when you try to log in? Also, have you been able to log in successfully before, or is this your first time trying?

In the meantime, here are some simple steps that often help with login issues on Goodnight:

1. Close the Goodnight app completely and then open it again.
2. Restart your iPhone to refresh the system.
3. Make sure your internet connection is stable—try switching between Wi-Fi and mobile data if possible.
4. If that doesn’t work, try uninstalling the app and then reinstalling it from the App Store.

If after trying these you still can’t log in, it may be helpful to check if your account is under any restrictions. Sometimes, login failures happen if an account has been banned due to policy violations like inappropriate content2.

Could you let me know which steps you've tried so far? That way, we can move on to deeper troubleshooting if needed.
