I’ve had great success with the Fingerprint api until ecently. Either the 28.0.0 client upgrade and/or my new iphone x (replacement device) is causing problems.
The first symptom was the iphone expo client application crashing (black screen, then return to desktop) when the
Fingerprint.authenticateAsync() was called. I upgraded my sdk version to 28.0.0 (and the react-native and the expo in my package.json) - and rebuilt to try again. Now it appears that when
Fingerprint.authenticateAsync() is called, I get a white screen prompting for the device passcode - but no FaceID.
Is anyone else experiencing this? The latter can be seen with a brand-new expo project that just shows a button that calls
app.json[expo.sdkVersion] = 28.0.0
Is anyone else seeing this?
