Unable to authenticate face after v1.3 update

Environment

• Knox Authentication Manager app v1.3

Issue

If device users previously registered their accounts with face sign-in on Knox Authentication Manager v1.2, then upgraded to v1.3 after registration, they would no longer be able to authenticate using the same face sign-in credentials.

Resolution

To resolve this issue, a device user must manually sign in to the Knox Authentication Manager app. On the failure prompt, they must tap Sign in.

Then, on the Knox Authentication Manager home screen, they must tap the menu button, then tap Re-register face.
