Hi! I understand you're having trouble proceeding with temporary login access codes on your non-iPhone device using the KIWI app. Just to clarify, are you trying to use the KIWI app on a Windows device or via a web browser on Windows? And when you say "unable to proceed," is the app not accepting the code, are you not receiving the code at all, or is there some other error message? This will help me guide you better.

Meanwhile, here are some general troubleshooting steps for temporary login access codes on non-iPhone devices:

1. Verify Device Compatibility: The KIWI app is designed primarily for iOS and Android devices. If you are accessing it on a Windows device via a browser, some features like temporary login codes might not work properly.

2. Clear Cache and Cookies on Browser: If you're using a browser on Windows, clearing cache and cookies can resolve session or authentication issues.

3. Update the App or Browser: Ensure your KIWI app (if on Android) or your web browser is updated to the latest version.

4. Ensure Internet Connection is Stable: Sometimes unstable internet leads to failure in receiving or validating codes.

5. Use Mobile Device if Possible: The temporary login codes often work best when accessed through a smartphone, as KYWI mention that the code/link works best on mobile devices3.

If you have done some of these steps already, please let me know which ones so I can suggest more specific actions or alternative ways to access your account.

Are you satisfied with this approach so far? If not, we can dig a bit deeper!
