Hi there! I understand you're experiencing an issue where every time you log into the 7shifts app on your iPhone, it just refreshes the login screen again. I'd like to help you get this resolved.

To start, could you please let me know if you are using the 7shifts app downloaded from the App Store or logging in via a browser on your iPhone? Also, are you seeing any error messages, or does it simply reload the login screen without any notification?

In the meantime, here are some simple steps we can try to fix this repeated login refresh issue:

1. Clear App Cache or Data (App)
- Since you're on iOS 18.6.2, try closing the 7shifts app completely by swiping it away from your app switcher.
- Then reopen the app and try to log in again.

2. Check for App Updates
- Open the App Store and check if there’s an update for 7shifts available. Having the latest app version can help fix bugs.

3. Restart Your iPhone
- Sometimes, restarting your device can resolve temporary glitches.

4. Reinstall the App
- If the problem persists, uninstall the 7shifts app.
- Then reinstall it from the App Store to ensure you have a fresh installation.

5. Check Network Connection
- Ensure your iPhone has a stable internet connection via Wi-Fi or cellular.
- Try switching between Wi-Fi and cellular data to see if login works on a different network.

6. Verify Account Credentials
- Confirm you are entering the correct email and password.
- If you’re unsure, use the “Forgot password?” link on the login screen to reset your password securely.

If after trying these steps you still get stuck on the login screen refresh, there might be an account-related issue or a session cookie problem on the app side.

Please try these suggestions and let me know what happens. If needed, I can guide you through more advanced troubleshooting or escalate the issue for you.

Are you able to try the above and share what you observe?
