Hi! I see you're encountering a black screen when trying to use Just Jumble on your Android device with WebKit browser. Let's figure this out together.

To start, can you tell me a bit more about when exactly the black screen appears? For example, does it happen right after launching the app or game, at a specific point in the puzzle, or after any update? Also, have you tried restarting the app or your device already?

Meanwhile, a common fix for black screen issues with apps like Just Jumble is to clear the app’s cache and data, which refreshes stored information that might be causing glitches. Here’s how you can try that on your Android 10 device:

1. Go to your device’s Settings.
2. Tap on Apps & notifications or simply Apps.
3. Find and select Just Jumble from the list.
4. Tap on Storage & cache.
5. Tap Clear Cache and then Clear Storage/Data (this resets the app, so you might lose saved progress if it’s not cloud-backed).
6. Close the settings and reopen Just Jumble to see if it works now.

If that doesn't help, uninstalling and reinstalling the app sometimes resolves deeper issues. Also, make sure your app is updated to the latest version from the Google Play Store.

If you’ve tried these steps or if the black screen occurs in the browser version, let me know. We can look into browser-specific fixes like clearing browser cache or checking for any browser settings that might interfere.

Does this sound good to start? Let me know what you’ve tried or observed!
