Hi there! I understand the Daily Express app on your Android device isn't opening. Could you tell me a bit more about what's happening? For example, does the app crash immediately, show a loading screen but never open, or give any error messages?

Meanwhile, I can suggest some common troubleshooting steps for the Daily Express app on Android 10 that often help:

1. Restart your device: Sometimes a simple reboot can clear minor glitches.

2. Clear app cache and data:
- Go to your device Settings > Apps or Apps & notifications.
- Find and tap on the Daily Express app.
- Tap Storage.
- First tap Clear Cache, then try opening the app.
- If that doesn't work, go back and tap Clear Data, but keep in mind this may erase saved app settings or login info.

3. Update the app:
- Open the Google Play Store.
- Search for Daily Express.
- If there's an Update button, tap it to install the latest version.

4. Reinstall the app:
- Uninstall the Daily Express app.
- Restart your device.
- Reinstall the app from Google Play Store.

5. Check your internet connection: Make sure you have a stable Wi-Fi or cellular data connection.

If you've already tried some of these, please let me know which ones so I can provide more targeted steps. Also, if the app freezes or shows any specific message, sharing that would really help.

Are you okay to try these steps and tell me how it goes?
