Okay Google from any Screen is not working on Galaxy S7 since update

[Android Central Question]

Hi @ all,
Okay Google workes when i tab on the Microphone and ask a question.
But it would not start by Voice from any screen.
Version Google App: 7.20.18.21.arm64
I already:
Changed the settings to say "ok Google" any time.
Retrained voice Model.
Disabled the S-Voice.
Closed all Apps.
Restarted the Phone.
Reinstalled Google App then installed older version. It worked initially til it updated again.

I'm on the same version and have noticed that I usually have to say it 2 or more times before it responds. It does eventually work in my case though.
