Hi! I see you're stuck in a login loop with the Carnival HUB app on your Windows device. Let’s work through this together to get you logged in smoothly.

First, just to clarify, when does the loop happen? Is it right after you enter your username and password, or does it cycle through the login screen repeatedly without proceeding? Also, have you tried logging in on another device or browser, or is this specific to your WebKit browser on Windows 10?

Meanwhile, here are some steps that usually help resolve this type of login loop:

1. Clear the browser cache and cookies: Since you are using the Carnival HUB app on Windows (likely via a browser), accumulated cache and cookies can cause login glitches. Clear these in your WebKit browser settings.
2. Double-check your login credentials: Sometimes a small typo or using a different email than the one registered could loop the login attempts. Confirm your email and password are correct.
3. Uninstall and reinstall the app: If you are using the dedicated Carnival HUB app on your Windows device (or if you have it installed as a Progressive Web App), uninstall it completely and then reinstall from the official source. This can often fix corrupt app data or faulty updates.
4. Try logging in on another device or browser: This can help pinpoint if the issue is device-specific or account-related.
5. Check for updates: Ensure both your browser and the Carnival HUB app are updated to the latest versions, as older versions can have bugs causing login loops.

If after these steps the problem persists, there may be a server-side issue or account-specific problem. In this case, contacting Carnival support directly via email at [email protected] would be the next best step.

Does this make sense so far? Were you able to try any of these already? I can guide you through these actions in more detail if you'd like.
