Logging in and using the app​

I was using the app but it says I have to take a selfie again. Why is this? 

I have feedback on the app. How can I share it?

What happens if I am registered for the Vanquis app and I lose my phone?

How do I use the new app to identify myself if I call Vanquis?

Can I turn my login biometrics on and off?

Can I change my selfie photo?

When I open the app it says there's been a problem. What does that mean?

The app says there’s scheduled maintenance. What does this mean?

Can I use the new app on a second device?

How do I delete the Vanquis app from my phone?

How do I log out of my account?

Now I am using the new app, can I delete the old one?

Why shouldn’t I have multiple people's fingerprints registered on my device?

I'm being advised I need to update the app but I can't. Can you help?

I was using the app but it says I have to enter my passcode again – why is this?
