Fingerprint not working on Pixel 2

[poblabs]

Hi there, I had a Pixel 1 and everything worked great - even on Android 8.

I got my Pixel 2 yesterday and the fingerprint portion isn't working within your app. I get a red exclamation error, and when I tap it I get the picture below. The app won't let me take a screenshot, so I used my Pixel 1 to capture the error on screen.

Let me know how else I can help debug?

Edit: I removed something that looked important within the screenshot. Not sure if it is or not, so erring on the side of caution.
