Hi there! I understand you're seeing a blank screen when trying to use the TBN Christian Streaming app on your Android device with WebKit browser. Let's work together to get this sorted out.

First, can you tell me a bit more about the situation?
- When did the blank screen issue start?
- Are you seeing this blank screen right after opening the app or when trying to play a particular video?
- Have you tried closing and reopening the app or restarting your device?
- Is your internet connection stable and working well with other apps or websites?

Meanwhile, here is a simple step-by-step approach to try:

1. Restart your device: Turn your Android device off and back on. This helps refresh the system.
2. Check your internet connection: Make sure your device is connected to a reliable Wi-Fi network or cellular data. Streaming can fail if the connection is weak or unstable.
3. Update the app: Go to the Google Play Store, search for the TBN app, and ensure it is updated to the latest version.
4. Clear the app cache and data:
- Go to Settings > Apps > TBN app > Storage
- Tap Clear Cache and then Clear Data (Note: Clearing data may log you out, so be ready to sign back in).
5. Try a different browser or device (if possible) to see if the problem persists; this helps determine if the issue is specific to your WebKit browser on Android 10.
6. Reinstall the TBN app: Uninstall and then reinstall the TBN app to ensure a clean installation.

If after these steps the screen remains blank, there may be a deeper technical issue, such as an app compatibility problem with WebKit on Android 10 or a temporary server problem at TBN's end.

Let me know what you’ve tried and how it’s going! If needed, I can guide you toward further advanced troubleshooting or how to contact support directly.

Are you satisfied with this guidance so far?
