why can't I unlock my phone using ok google trusted voice vivo v3

[Android Central Question]

I just download google now and it would be nice if I can work on any screen. I can't do that. It says "could not retrieve settings. Please try later "

Make sure you are logged in to the same Google account that you set up the Google now with. There is a security checkbox in settings you must tick also to allow to unlock from lock screen using voice.
