Facial Recognition Unavailable on Honor 9 After Update

[ThisBoyAwesome]

Hi, I am using Honor 9 Lite from a couple of months and also enjoying the new feature of Facial Security of it but now after OTA update this feature "Facial Recognition" sometimes not work properly. It may b due to update of OTA but now I want to solve it anyway please can anybody tell me how to fix it.

Mine still works fine and also wife and 2 kids who all have 9 lites. It generally needs fairly decent light but not noticed any fault over all the updates I've had up til now.
