If you previously used your fingerprint or face to log into the Virgin Money Credit Card app and it has stopped working, follow these steps the next time you log in:
• Tap the profile icon at the top of the app
• Select ‘Sign in and security’
• Use the toggle on the right-hand side to enable biometric login
If the toggle is already switched on, turn it off, then turn it back on again to reset it.

I've followed instructions to turn on biometric login, each time I try to log back in I get err message Biometric login unavailable - what's wrong please?
