Research direction

Start by reproducing the reported Challenge Response unlock failure in Keepass2Android 1.14 with a YubiKey 5 NFC on Android 16, then compare it with Android 13 where it worked. Check whether the reported “no valid challenge” message is caused by the Android 16 environment; done means identifying a reproducible cause and either restoring unlock behavior or documenting the incompatibility and workaround.
