Hi! I’m Daniel Otega, here to help you get your Babbel app working again on your Android device. When you say the app "won't open," can you tell me a bit more? For example, does the app crash immediately, just show a blank screen, or does nothing happen when you tap the icon?

In the meantime, here’s a straightforward checklist that usually solves these kinds of issues on Android 10 with WebKit browser environment:

1. Force Close the App:
- Go to Settings > Apps > Babbel
- Tap "Force stop" to fully close the app if it is running.

2. Clear Cache and Data:
- Head back to Settings > Apps > Babbel > Storage
- Tap "Clear cache" first, then check if the app opens.
- If it still won’t open, try "Clear data" (this will log you out but can fix corrupted files).

3. Check for Updates:
- Open Google Play Store, search Babbel, and make sure you have the latest version installed. Updates often fix bugs.

4. Restart Your Device:
- Simple but effective. Restarting can clear temporary glitches.

5. Check Your Internet Connection:
- Babbel requires an active internet connection to load. Try switching Wi-Fi on/off or try mobile data.

If after trying these the problem persists, sometimes uninstalling and reinstalling the app can help clear any installation issues without losing your subscription data.

Let me know which steps you've already tried or if the app behaves in a specific way when you open it. We’ll figure this out together!

Also, you can find detailed troubleshooting on the official support page here: Babbel app or website isn't working 1.
