Hi,
When you create a relationship field in ACF, how do you then use this sort order to display the related on a page?

This is my code:

<?php  
	 $args = array(
		'post_type' => 'client',
		'posts_per_page' => '8',
		'post_status' => 'publish',
		'orderby' => 'rand',
		
	);
	query_posts($args);
	while ( have_posts() ) : the_post();
		 $cliente = get_the_title();
		 $logo_hover = get_field('logo_hover');
         $logoclient = get_field('logo');
		 $id = get_the_ID();
		
		 $case = get_posts(array(
			'post_type' => 'casestudy',
			'meta_query' => array(
				array(
					'key' => 'cliente', // name of custom field
					'value' => '"' . get_the_ID() . '"', // matches exaclty "123", not just 123. This prevents a match for "1234"
					'compare' => 'LIKE'
				)
			)
		));
	 ?>  
	<?php if( $case )  ?>
				<div class="brand">
				<?php
				if (count($case) > 0) {
					foreach( $case as $cliente2 ): 
						if (count($case) == 1) {
						?>
						<a href="<?php echo get_permalink( $cliente2->ID ); ?>">
							<img class="img-cliente" src="<?php echo $logoclient['url']; ?>" alt="<?php echo $logoclient['alt']; ?>" />
                        <img src="<?php echo $logo_hover['url']; ?>" alt="<?php echo $logo_hover['alt']; ?>" />
						</a>
						<?php
						} else {	
						?>
						<a href="<?php echo get_permalink( $case->ID ); ?>">
							<img class="img-cliente" src="<?php echo $logoclient['url']; ?>" alt="<?php echo $logoclient['alt']; ?>" />
                       	 <img src="<?php echo $logo_hover['url']; ?>" alt="<?php echo $logo_hover['alt']; ?>" />
						</a>
						<?php
						}
					endforeach;
				} else {
				?>	
					<a href="javascript:void(0)" style="cursor:default;">
						<img class="img-cliente" src="<?php echo $logoclient['url']; ?>" alt="<?php echo $logoclient['alt']; ?>" />
                        <img src="<?php echo $logo_hover['url']; ?>" alt="<?php echo $logo_hover['alt']; ?>" />
					</a>
				<?php
				} 
				?>						
 				</div>
    <?php
    endwhile;
	wp_reset_query();
    ?>

Try changing these to lines:

if (count($case) > 0) {
  foreach( $case as $cliente2 ): 

to

if (count($case->posts) > 0) {
  foreach( $case->posts as $cliente2 ): 

I don’t understand what you’re trying to do here

<a href="<?php echo get_permalink( $case->ID ); ?>">

$case in your code is a WP_Query object, so $case->ID has no value.

To get a better idea of what $case holds you can do this so that you can see everything that’s in it.

echo '<pre>'; print_r($case); echo '</pre>';
