Idea to avoid preloading font warning

Preloading the font is ok unless it’s not being used. Then chrome clomplain:

The resource /plugins/rate-my-post/public/css/fonts/ratemypost.ttf was preloaded using link preload but not used within a few seconds from the window's load event. Please make sure it has an appropriate as value and it is preloaded intentionally.

So this is what worked for me: using to preload only on single post.

add_action( 'wp', function() {
if ( ! is_singular() ) {
add_filter( 'rmp_font_preload', '__return_false' );
}
});

I don’t think this applies to everyone, though.
