Bank App Your Face Is Invalid

I'm trying to register my new device on the App but i cannot get past the take-a-selfie stage of the install process. It is basically telling me my face is invalid - nice going assholes!

I've highlighted this idiotic feature previously but have yet to receive any intellectual feedback on the matter. I've been an discovery card client for more than a decade and i'm absolutely discussed by lack of service i have received during this transition period.
