Hi there! I’m sorry to hear the O2 Venue App is opening but showing a blank screen. Let’s see if we can get it working for you.

Could you tell me a bit more? For example, are you using the app on your Windows 10 device through a browser with WebKit, or is this a standalone app? Also, have you tried closing and reopening it, or restarting your device yet?

Meanwhile, here are some general steps that often help with this kind of issue:

1. Clear the browser cache: Sometimes cached files cause problems. You can clear cache by going to your browser’s settings and finding 'Clear browsing data' or 'Clear cache.' Make sure to only clear the cache and not passwords or history if you want to keep those.

2. Update the browser: Ensure your browser is updated to the latest version. Older versions can have compatibility issues.

3. Disable browser extensions: Sometimes extensions interfere with apps loading properly. Try disabling them temporarily and then reload the app.

4. Check your internet connection: A weak or unstable connection can cause pages to stay blank.

5. Try a different browser: Although you’re on WebKit, testing with another browser like Chrome or Edge could help identify if the problem is browser-specific.

If you’ve tried any of these already, let me know so I can suggest next steps!

I am using it on my mobile phone. I have restarted the app multiple times and even reinstalled it twice

Thanks for letting me know you’re using the O2 Venue App on your mobile and that you’ve already reinstalled and restarted it a couple of times. That’s helpful info!

Sometimes, even after reinstalling, some app data or cache might cause loading problems. Could you try clearing the app’s cache and data through your phone’s settings? Here's how you can do that on Windows-based mobile (if applicable) or relevant smartphones:

1. Go to your phone’s Settings.
2. Find Apps or Applications.
3. Scroll to locate the O2 Venue App.
4. Tap on it and select Storage.
5. Choose Clear Cache first, then try reopening the app.
6. If that doesn’t work, you can try Clear Data (note: clearing data may log you out and delete app settings).

If the app still shows a blank screen after that, please check:

- Are you logged in with the same email you used to buy tickets? Sometimes, using a different account can cause issues.
- Is your mobile data or Wi-Fi connection stable and working properly?
- Double-check that you have the latest version of the app installed from your app store.

If these steps don’t resolve it, an alternative is to use the AXS app, as the venue uses AXS for their ticketing system regardless1. That might be a good fallback until the issue is fixed.

Let me know what happens after trying these, and I can guide you further! Are you comfortable checking the app’s storage settings on your phone?
