Hi! I see you’re having trouble with the NZeTA app showing a blank black screen on your device. Let’s work through this together.

To help me understand better, could you tell me:
- When did the black screen issue start?
- Are you able to open the app at all, or does it immediately show the black screen?
- Have you tried any fixes so far, like restarting the app or your device?

In the meantime, here are some steps you can try on your Windows device with the WebKit browser to resolve an app showing a black screen:

1. Force close and restart the app
- Close the NZeTA app completely. You can do this by opening Task Manager (Ctrl + Shift + Esc), finding the app process, and ending it.
- Wait about 10 seconds and then reopen the app.

2. Clear app cache (if possible)
- Sometimes cached data might cause display issues. If the app allows clearing cache in settings, do that. Otherwise, you might need to reinstall the app.

3. Update the app
- Check if there’s a newer version of the NZeTA app available and update it to ensure any bugs are fixed.

4. Reinstall the app
- Uninstall the app completely, then download and install it again. This often clears corrupted files causing black screen problems.

5. Check network connection
- The app might fail to load properly if your connection is unstable. Try switching to a different Wi-Fi network or use a wired connection if possible to test.

6. Try using the web version
- If the app continues showing a black screen, you might want to access NZeTA services via their website as a temporary workaround.

If these steps don’t help, there may be a deeper issue with the app's compatibility or a service outage. Let me know how these go, and if you’ve tried any already, please share so we can dig deeper!

Are you able to try these now?
