I’m not sure how this is working correctly at all by looking at the code you’ve provided
<?php switch_to_blog(2); // ACF will be using the current post ID here // that current post ID is the post on the current site which may // be a different post with the same ID on the site you are switching to // I can only guess that this is somehow causing the post ID to get lost $tallimage2 = get_field('tall_image_2'); if( $tallimage2 ): ?> <img src="<?php echo $tallimage2['image2']; ?>"> <p class="mb0"><?php echo $tallimage2['caption2']; ?></p> <?php endif; ?> <?php restore_current_blog(); ?>
I would start by seeing what the post is before and after your call by outputting the global $post value before and after
global $post; echo '<pre>'; print_r($post); echo '</pre>';
