Hi Jose,
Thank you very much for your answer and sorry for my late reaction. It wokrs, great! Before I had this, it worked but it was not the right way:
<?php while (have_posts()) : the_post(); ?>
<?php if ( is_sticky() ) :
get_template_part( 'content-sticky', get_post_format() );
?>
<?php else : ?>
<?php break; ?>
<?php endif; ?>
<?php endwhile; ?>
Your code seems to be the way! Thank you so much
