Hi there! I understand you're seeing a message saying your login is no longer valid every time you open The Study Bible app on your iPhone running iOS 18.6, and when you tap OK, it takes you to your account. Let me help you get this sorted out.

To start, can you tell me if this started happening recently after any updates or changes to your device or the app? Also, have you tried any steps already to fix it, like signing out and back in or restarting your phone?

Meanwhile, here are some common, effective steps to try for login-related issues on The Study Bible app:

1. Restart the app: Close it completely and open it again. This refreshes the app and can clear temporary hiccups.

2. Sign out and sign back in: Since it takes you to your account page, try logging out fully from the app, then sign back in with your credentials. This often resets session info.

3. Check for app updates: Visit the App Store to make sure you have the latest version of The Study Bible installed, as updates often fix login and sync problems.

4. Restart your iPhone: Sometimes a quick reboot resolves temporary glitches with apps or iOS.

5. Clear app cache if possible: Although iOS apps don’t always let you clear cache manually, reinstalling the app can help:
- Delete The Study Bible app.
- Restart your iPhone.
- Reinstall the app from the App Store.
- Log in again.

6. Check your internet connection: Make sure your iPhone is connected to a stable Wi-Fi or cellular network, as login verification requires internet access.

If these don't help, it might be related to your account specifics or a server-side issue. Then, I can help you reach out to our app support team at [email protected] for deeper investigation.
