Hi there! I understand that when you click on the ZBD app, the screen isn't visible. Let’s work through this together.

To start, can you tell me if the app opens at all? For example, do you see a splash screen or any loading indicator, or does it just stay blank or black? Also, have you tried any steps already, like restarting the app or your device?

Meanwhile, here are some initial steps to try:

1. Force Close the App:
- Since you're on Android 10 with a WebKit device, open the recent apps screen (usually by swiping up from the bottom or tapping the recent apps button), then swipe the ZBD app away to close it fully. Then open it again.

2. Restart Your Device:
- Sometimes, a fresh start can resolve display issues.

3. Clear App Cache and Data:
- Go to Settings > Apps > ZBD
- Tap Storage
- Select Clear Cache
- If that doesn’t help, try Clear Data (note this may log you out and reset app settings).

4. Check for Updates:
- Visit the Play Store and ensure the ZBD app is up to date.

If you’ve done these or the issue persists, we can try more advanced options like reinstalling the app or checking if any permissions might block the display.

Let me know what you tried and what you see when you open the app! That way, I can guide you better for your specific situation.

Are you ready to try these steps?
