If your Lufthansa app is stuck on loading the Travel ID with no result, follow these steps for troubleshooting:

1. Check Internet Connectivity
Ensure your internet connection is stable. If using Wi-Fi, try switching to cellular data, or vice versa.

2. Update the App
Check for any available updates for the Lufthansa app in the Microsoft Store. An outdated version could cause loading issues.

3. Clear Cache and Data
Clear the app’s cache and data. Go to Settings > Apps > Lufthansa app > Storage, and select the options to clear cache and data. This can help resolve loading problems.

4. Restart the App
Close the app completely by using the task manager, then reopen it.

5. Log Out and Log Back In
Sometimes, logging out and then logging back in solves issues related to app data. Open the app, go to settings, log out, and then log back in with your credentials.

6. Check Travel ID Registration
If it's been less than 24 hours since you registered for a Travel ID, check your email (including spam folders) for an activation link. Make sure your Travel ID is activated correctly - learn more.

7. Wait for Check-in to Open
If you're trying to load your Travel ID during a time when check-in is not available, wait until it opens. Consider using the scan ID feature when it becomes available - learn more.

8. Try a Different Device or Browser
If the problem persists, try accessing your Travel ID on a different device or through a web browser, which might provide better functionality than the app.

9. Contact Customer Support
If none of the above steps work, contact Lufthansa customer support. Provide details of the problem using their feedback form available on the Lufthansa website - learn more.

Following these steps should help resolve the loading issue with your Travel ID in the Lufthansa app. If you continue facing problems, it may indicate a larger system issue that Lufthansa’s technical support can address.
