Crawling Delay

Hi,

After several attempts finally RSS feeds works, thanks to GN Publisher and this forum.

I’ve successfully used this form of feed: https://www.hifipertutti.it/?category_name=hifi-news&feed=gn

However, gnews is very slow updating new articles, i’ve added the following lines in functions.php to disable RSS cache:

//disable rss feed cache

function turn_off_feed_caching( $feed ) {
    $feed->enable_cache( false );
}
add_action( 'wp_feed_options', 'turn_off_feed_caching' );

//DISABLE RSS FEED CACHE END

//featured image in rss feed

function featuredtoRSS($content) {
global $post;
if ( has_post_thumbnail( $post->ID ) ){
$content = '<div>' . get_the_post_thumbnail( $post->ID, 'full', array( 'style' => 'margin-bottom: 15px;' ) ) . '</div>' . $content;
}
return $content;
}
 
add_filter('the_excerpt_rss', 'featuredtoRSS');
add_filter('the_content_feed', 'featuredtoRSS');

//END FEATURED IMAGE IN RSS FEED

Any suggestion?
