Yoast SEO how to allow crawler bot

Question

I got a job to get rid of "No information is available for this page" in a website. The website uses Yoast SEO, but it was disabled so I reenabled it and then I got a basic robots.txt like this

User-agent: *
Disallow: /wp-admin/
Allow: /wp-admin/admin-ajax.php

I have applied that settings for about six hours ago, tried to search it in Google, and still nothing changed. I feel anxious now. Is this enough for the crawlers to read the website? Do I miss something? Do I need to mess with .htaccess? I have zero exp in SEO, so any help would be very appreciated.
