HI there,
Thanks for using Yelp Reviews Pro! Yelp serves the reviews to your website in a custom order that they call “Most Helpful”. This means that the LATEST reviews won’t get served to your website until Yelp decides that they are considered “Most Helpful”.
Also, I’d like to let you know that we are in the middle of totally revamping how we do Business Reviews as a whole. If you’re interested in learning more about what we’ve got up our sleeves and maybe doing some beta testing for us, feel free to sign-up here: https://wordimpress.com/wp-business-reviews-beta-sign/
Let me know if you have further questions. Thanks!
