Hi there! I understand you're having trouble registering or logging into the Goodnight app on your iPhone running iOS 18.6.2. Let's see if we can get that sorted out.

To get started, could you please tell me:

- Are you trying to register a new account or log into an existing one?
- Are you seeing any specific error messages when you try to register or log in?
- Have you been able to use the app successfully before on this device or is this the first time?
- Have you tried any steps already, like restarting the app or your phone?

Knowing these details will help me guide you better. Meanwhile, here are some quick checks you can try if you haven’t yet:

1. Close the Goodnight app completely and restart it.
2. Reboot your iPhone to refresh the system.
3. If those don't help, uninstall and then reinstall the Goodnight app from the App Store.

If the problem persists after these, there might be account-specific issues or a temporary platform restriction we need to look into.

Let me know what happened when you tried these or any error messages you saw!

I already deleted the app a month ago and every time I enter it’s jun the loading circle and it says that I cannot register

Thanks for the extra info! Since you've reinstalled the Goodnight app but it just keeps stuck on the loading circle and won’t let you register, it sounds like something is blocking the connection or registration process. Let’s try a few targeted steps:

1. Check Internet Connection: Make sure your iPhone is connected to a stable Wi-Fi or cellular network. Sometimes a weak or unstable connection causes apps to hang. Try switching between Wi-Fi and cellular data to see if it makes a difference.

2. Clear App Data via iPhone Settings: Although iOS doesn’t provide direct cache clearing for apps, try this:
- Go to Settings > General > iPhone Storage > Goodnight.
- See if there's an option to offload the app. Tap Offload App (this deletes the app but keeps its data) then reinstall it.
- Alternatively, deleting and reinstalling app again here can sometimes clear residual data not cleared before.

3. Check Date and Time Settings: Make sure your date, time, and time zone are set to automatic.
- Go to Settings > General > Date & Time, and toggle on Set Automatically.

4. Verify App Permissions: Sometimes permission issues prevent apps from communicating.
- Go to Settings > Goodnight, and ensure necessary permissions like network access are allowed.

5. Restart Your iPhone: You may have done this, but it’s worth another try after reinstall and permission checks.

6. Try Registering Using a Different Method: If Goodnight has options to register via email, phone number, or social sign-in, try an alternate method in case one is temporarily down.

7. Update iOS: Your iOS 18.6.2 is current, but double-check for any minor updates under Settings > General > Software Update.

If after all these, the app still hangs on loading and won’t let you register, there might be a server-side issue or account block. In that case, I would recommend contacting Goodnight's support team directly at [email protected] to check your account status or report the problem1.

Please try these and let me know how it goes! Are you satisfied with the solution I provided so far?
