App lock (local authentication) can't be turned on on Android

On Android, switching on "Enable local authentication" in settings does nothing. The setting stays off and no fingerprint or PIN prompt appears.

Reported on a Samsung S25 running Android 16 (One UI 8.5). It works on iPhone.

    This is fixed in 1.78.0, out now. Enabling local authentication now brings up the fingerprint or PIN prompt and the setting sticks. If the prompt is refused, the app now says so rather than silently doing nothing. Please let me know if that works for you.
