Fingerprint Authentication UI issue Android

Issue:
When launching the app, the Home tab is briefly shown before the fingerprint authentication appears.

I think this has been brought up before. Last I heard it was being investigated but that was a while back.

I’ve experienced this behaviour since they first introduced fingerprint authentication

I’ve experienced this on my Pixel 2 XL as well since the Android 9/Pie update. From my understanding app developers should be using the BiometricPrompt API from Pie onward to show authentication dialogs (per https://android-developers.googleblog.com/2018/06/better-biometrics-in-android-p.html).

Obviously we’ll be a tiny sliver of the user base at the minute so I guess this will be quite low on the list of priorities (and I’m also assuming switching to this would fix the issue)!

Edit: It’s in the support library as well though so it can support < Android P too!
