Hi there! I understand your Carnival HUB app keeps logging you out, and you'd like to get that fixed. That can be inconvenient, so let's work through it together.

First, just so I’m clear, is the app logging you out immediately after you log in, or is it after some time of use? Also, have you noticed if it happens only when connected to specific networks (Wi-Fi or cellular data)? Have you tried any fixes yet, like reinstalling the app or clearing its cache?

Meanwhile, here's a step-by-step guide you can try on your WebKit-based Android 15 device:

1. Clear App Cache and Data:
- Go to Settings > Apps > Carnival HUB on your device.
- Tap Storage & cache.
- Tap Clear Cache and then Clear Storage/Data. This will reset the app and potentially fix login issues.

2. Update the App:
- Open the Google Play Store and check if there is an update available for the Carnival HUB app. An outdated app can cause login loops.

3. Reinstall the App:
- Uninstall the Carnival HUB app completely.
- Restart your device.
- Reinstall the app fresh from the Play Store.

4. Check Network:
- Ensure you have a stable internet connection.
- Try switching between Wi-Fi and mobile data to see if the issue continues.

5. Login Method:
- When logging back in, make sure to use the main “Log In” option and not the “I’m On Board” or “Enter With Booking #” shortcuts, as these can sometimes cause issues.

If after these steps it keeps logging you out or going into a login loop, it could be tied to server-side issues or an account-related problem. At that point, I would suggest verifying if Carnival HUB service is experiencing outages or contacting Carnival support directly via [email protected] for account-specific help.

Let me know what you’ve tried so far or if you want me to walk you through any of these steps! Are you satisfied with this approach so far?
