Hi there! I see you're encountering a "Login error null" with Readink on your iPhone running iOS 18.5. Let’s get a bit more detail so I can assist you better:

- Are you receiving this error when you try to log in through the app or the web browser?
- Did this error start recently, or has it been ongoing?
- Have you already tried any steps like restarting the app or your phone?

Once I know that, I can walk you through some targeted steps to resolve it. Meanwhile, a common cause for "null" login errors is an issue where the app tries to read information but finds nothing (null value), often due to data not loading properly or a temporary glitch in the app.

A good starting point would be:

1. Force close the Readink app on your iPhone (swipe up from the bottom and pause, then swipe the app off the screen).
2. Restart your iPhone to clear any temporary system issues.
3. Open the Readink app again and try logging in.

If that doesn’t help:
4. Check your internet connection (Wi-Fi or cellular) to ensure it’s stable and working well for other apps or websites.
5. If possible, update the Readink app from the App Store to ensure you have the latest version. Sometimes bugs causing errors like these are fixed in updates.
6. You could also log out and log back in if the app allows that without error, or reinstall the app entirely (press and hold the app icon, delete it, then reinstall).

Let me know if you’ve tried any of these steps or if the error shows any additional messages. I’m here to get this resolved for you!

Logging into app, yes I have restarted app and phone. I have the latest version of the app. It started this morning.

Thanks for the extra info! Since you've already restarted the app and your phone, you have the latest app version, and the login error started just this morning, it suggests this could be a temporary issue related to the app servers or your account data.

Here are some focused next steps for you to try:

1. Check Internet Connection Again: Even if it looks fine, try switching between Wi-Fi and cellular data to see if one works better during login.

2. Log In Through a Browser: Visit Readink’s website on Safari or another browser on your iPhone and try logging in there. If it works on the browser but not the app, that confirms an app-specific issue.

3. Reinstall the App: Since the app is latest but the issue persists, try deleting the app completely and reinstalling it. This can clear hidden corrupted data.

4. Check for Announcements: Sometimes app providers perform server maintenance or update something that causes login issues temporarily. You might check Readink’s social media or notifications for any scheduled downtime.

5. Try a Different Account (if possible): To isolate if it’s your account causing the issue, you could try logging in with a different Readink account on your device.

If none of these help, it’s likely something affecting your account or Readink’s server side that we can’t fix from your device. In that case, I recommend reaching out directly to Readink support via [email protected] with details about your iOS version, app version, and exact error message.

Let me know how these go, or if you want me to help further! Are you satisfied with these next steps?
