Hi! I see you're experiencing an error with the DartCounter app not working. To help you better, could you please tell me a bit more about the error? For example:
- What exactly does the error message say, if any?
- When does the error occur (e.g., on app launch, logging in, during a game)?
- Have you tried any steps so far to fix it?

This way I can guide you more precisely. Meanwhile, here are some initial steps you can try on your Android 10 device with WebKit browser:

1. Check Internet Connection
Make sure your device has a stable internet connection (WiFi or mobile data). The app needs connectivity to work properly.

2. Clear Cache and Data of the App
- Go to Settings > Apps > DartCounter
- Tap on Storage
- Tap "Clear Cache" and then "Clear Data"
- Restart the app and see if it works.

3. Update or Reinstall the App
Sometimes a fresh install fixes lingering issues:
- Uninstall the DartCounter app
- Reboot your device
- Install the latest version from Google Play Store or the official site
- Open the app and try again.

4. Check for Server Issues
Occasionally, the DartCounter service may have temporary problems. You can check their status or recent notices on their site or social media. For example, some users had connectivity issues reported recently, but they often resolve quickly1.

If these don't fix the problem, please let me know the exact symptoms or screenshots if possible, so I can suggest the next steps or unlock deeper diagnostics.

Are you satisfied with this direction so far?
