Hello! I understand you're having trouble creating your BoursoBank account because the app disconnects when you upload your ID card. Let's work together to sort this out.

To start, can you tell me if you are using the BoursoBank app or accessing the account creation through a web browser on your Android 10 device? Also, is your internet connection stable when uploading the ID?

In the meantime, here are some initial steps you can try:

1. Check Your Internet Connection: Ensure you have a strong, stable Wi-Fi or mobile data connection during the upload.

2. Clear App Cache (if using the app):
- Go to your device's Settings > Apps > BoursoBank > Storage > Clear Cache.
- Then restart the app and try again.

3. Update the App: Make sure you have the latest version of the BoursoBank app from the Google Play Store. Sometimes glitches happen if the app is outdated.

4. Try a Different Browser or Use the App: Since you are on a WebKit browser, sometimes switching to another browser like Chrome or using the official app can help.

5. Ensure Your ID Card Image is Clear and Within Limits:
- The image should be well-lit, clear, and in the required format (usually JPG or PNG).
- Also, check if the file size is within the allowed limit (usually a few MBs).

If you have tried all these and still get disconnected after uploading your ID, please let me know. We can then check for any server-side issues or try other advanced troubleshooting steps.

Are you currently connected to Wi-Fi or mobile data when uploading your ID?
