Hi! I see you're having trouble with Face ID on the Avant app and it's showing "Biometrics not enrolled." I'd love to help you get this sorted out. To start, can you tell me if you've already set up Face ID in your Windows device settings? Also, is the Avant app updated to the latest version?

Meanwhile, here are some basic steps you can try to fix the "Biometrics not enrolled" error:

1. Confirm Biometrics Are Enabled on Your Device:
Even though your device is Windows 10 with WebKit browser, Face ID is typically a feature on mobile devices, often iOS or Android. If you are using a device that supports Windows Hello facial recognition, make sure it’s set up properly:
- Go to Settings > Accounts > Sign-in options.
- Check under Windows Hello Face if it says "Set up" or "Recognized your face."
- If not set up, follow the prompts to enroll your face for Windows Hello facial recognition.

2. Check Avant App Settings:
Open the Avant app and navigate to the app's settings. Look for biometric login or Face ID options and verify if they are enabled. If they are off, toggle them on and try logging in again.

3. Restart and Reinstall:
- Restart your device to refresh system processes.
- If that doesn’t help, uninstall and reinstall the Avant app to clear any corrupted cache or settings related to biometrics.

4. Ensure You Have a PIN or Password Set:
Many biometric features require a fallback method, like a PIN or password, to be set on your device account. Check in Windows security settings if you have a PIN or password configured.

If your device itself doesn’t support Face ID or Windows Hello face recognition, that would explain the “Biometrics not enrolled” message. In that case, the app won’t recognize any biometric hardware on your device, and alternative login methods will be needed.

Could you confirm if you're using Windows Hello face recognition or any biometric feature on your device already? That will help me suggest the best next steps.
