Stop review output in the_content()

I’ve tried the following code in my theme’s functions.php file but it isn’t working.
remove_filter('the_content', array('WPCustomerReviews3', 'do_the_content'), 15);

Hello,

Did you manage to get this resolved? I am having the same issue.

Trying to put it somewhere using a page builder but it appears again underneath the page content.

Same issue , check a fix I’m using:
