Customize main menu icons in mobile

Could be cache. It works for me though: https://s33.postimg.org/7yyb9lr5r/2017-11-15_0844.png

Yes, it works on the main page ... but something has been deconfigured ... in the mobile version the menu appears as an error:

Let's try using the snippet only on the front page:
add_action( 'wp_enqueue_scripts', 'generate_dequeue_mobile', 100 );

function generate_dequeue_mobile() {
   if ( is_front_page() ) {
       wp_dequeue_style( 'generate-mobile-style' );
   }
}

Yes, now it works! Thanks Leo for your patience!

No problem! Thanks for your patience too!
