Hi there! I see your TabTrader app won’t open on your Android device with WebKit, version 10. I’d like to help you get it running smoothly again. To start, could you tell me if you see any error messages when you try to open the app, or does it just stay on a blank screen or crash immediately? Also, have you recently updated the app or your Android OS?

Once I have that info, here are some initial steps that usually help with this kind of problem:

1. Restart Your Device: Sometimes a simple reboot clears up temporary glitches.

2. Update the App: Check the Google Play Store to see if there’s an update available for TabTrader. Running the latest version keeps things stable.

3. Clear Cache & Data:
- Long press the TabTrader app icon on your home screen or app drawer.
- Tap "App info."
- Go to "Storage & cache."
- Tap "Clear cache."
- If that doesn't help, try "Clear storage" or "Clear data" (note this might reset app settings, so back up anything important).

4. Check Internet Connection: Make sure you have a stable internet connection, Wi-Fi or mobile data.

If you already tried any of these, please let me know, and we can try some more advanced troubleshooting. Also, if the app still won’t open, I can help you check for any known server issues or bugs.

Would you like to start with these steps?
