Fingerprint ID with Double Tap to Sleep

[matthewfox1972]

So I have a new Xperia X. I have set up fingerprint ID authentication which works well. I toggled the option in the home screen settings to enable 'double-tap to sleep' and when I do that, the screen turns off but the fingerprint authenitcsation doesn't work - i.e. I am forced to unlock the phone using the PIN method.

Is this a bug, or just something quirky that I am doing?
