I'm having a similar issue with fingerprint authentication in apps; most notably all apps in the shelter work profile that use this feature.
Unlocking the phone using fingerprint works like a charm, so no issues there.
The fingerprint authentication feature in apps within the shelter work profile, however, completely broke after the updates this week. I'm not sure which one, but all was fine last week Saturday.
My banking app stopped asking for fingerprint all together, even though it is enabled (and has been enabled since day 1) in the settings. Another app does come up with the fingerprint prompt, but when successfully authenticating the fingerprint does not follow through and stays on the logon screen, forcing me to put the pin code. There's also an app that at first doesn't show the fingerprint prompt and forces a pin code, but after putting in the correct pin code suddenly shows the fingerprint prompt.
I tried disabling and re-enabling fingerprint authentication, both in OS or apps, to no effect.
It does seem to correctly authenticate the fingerprint presented, because providing the wrong print does give the 'invalid print' result. Correct prints seem to satisfy the fingerprint prompt but nothing happens from that point on.
Does anyone have the same issues or maybe even a solution?
