Hide Date and Update Snippet Description

[AngoraSpace]

Dear All

I want to hide all the date from snippet and search engine.
I've set this with Yoast but the date still appear on Google.
What should I do to remove all the date from all search engine?

And I want my description snippet regarding from post content.
Not prev / next post, copyright, social media, etc.
So, what should I do now?



Also I take this screenshot.

Pic above is taken from my dashboard.
The snippet is right regarding to what I want.
The description snippet is regarding to my post content.

Pic below is taken from search engine result.
There is the date with random unwanted description.



Regards
