Hi there! I understand that both the Wizz Air website and app haven't been working well for you since yesterday. Let's try to get this sorted out together.

Could you tell me more about what exactly happens when you try to use the app or website? Are you seeing any error messages, or does it fail to load entirely? Also, are you experiencing problems with certain features like booking, check-in, or login?

Meanwhile, I can share that there have been reports recently about Wizz Air’s servers being temporarily overloaded or unreachable, which causes issues with both the site and app. This might be what you’re facing.

Here's a simple step-by-step approach we can try right now on your Android 10 device with the WebKit browser:

1. Clear Cache and Cookies: Sometimes, stored data can cause loading problems.
- Go to your browser's settings.
- Find "Privacy" or "Site settings."
- Clear cache and cookies for the Wizz Air website.

2. Update or Reinstall the Wizz Air App:
- Open Google Play Store.
- Search for Wizz Air.
- If an update is available, tap update.
- If it’s already updated or still not working, uninstall and reinstall the app.

3. Try Using a Different Network:
- If you’re on mobile data, try connecting to a Wi-Fi network.
- Or switch from Wi-Fi to mobile data.

4. Restart Your Device: This can refresh system processes that might impact app or browser performance.

If none of these work, the problem might be on Wizz Air’s end due to server overload or network issues, and waiting for them to resolve it could be necessary. You can check real-time outage status on sites like "isitdownrightnow" or "Downdetector" to confirm if Wizz Air is experiencing downtime.

Would you like me to guide you through any of these steps? Also, please let me know if you get any specific error messages or behaviors so I can assist further.

Are you satisfied with this initial plan?
