Hi there! I understand you're having trouble logging into the Nectar app on your iPad, specifically with the access code step where after receiving the code and returning to the login screen, it just takes you back to "login again." I'd love to help you get this sorted out.

To start, can I ask a few quick questions to understand better?
1. Are you using the latest version of the Nectar app on your iPad?
2. Is your iPad connected to a stable internet connection when you try to log in?
3. Does the access code you receive arrive promptly, and when you enter it, do you get any error message or does it simply refresh to the login screen?

Meanwhile, here’s a general step-by-step approach that often solves this kind of login loop with access codes:

1. Check your Internet connection: Make sure your iPad is connected to a reliable Wi-Fi or cellular network. Connectivity issues can interrupt the login process.

2. Update the Nectar app: Open the App Store, go to Updates, and ensure the Nectar app is updated to its latest version.

3. Restart your iPad: Sometimes a simple restart helps clear temporary glitches.

4. Clear app cache (if possible): On iOS, you may need to delete and reinstall the app to clear cache and data.

5. Ensure the access code is entered quickly: The code sent for login often expires within a few minutes for security reasons. Enter it as soon as you get it.

6. Disable VPN or any proxy: If you are using VPN or proxy settings on your iPad, try disabling them, as they sometimes cause login issues due to security filters.

7. Try logging in on another device or via a browser: This helps check if the issue is app-specific or account-related.

If you’ve tried all this and still face the loop, there might be an issue with the multi-factor authentication (MFA) setup or a security block on the account, which may require contacting Nectar support for deeper assistance.

Let me know where you are with these steps or if you notice any specific messages. I’m here to guide you further!

Are you satisfied with the solution I provided so far?
