[Android] "RSA private or public key is null" error when approving transaction via fingerprint

[phildawson (Sorry, I will have to escalate this.)]

I was revealing the card number a couple of times for helping in this thread when it happened.

Show card number - copy to clipboard

Are you tap and holding on the row of numbers, the hit area is quite tight around the numbers so a little too high or low on the card and it won’t work. Basically just tap an hold any white 16 long card number and no hot coral. Does that work?
