Ok, thank you.

I came up with a new solution just to count the number of values inside the two arrays:

    add_action('acf/save_post', 'my_project_updated_send_email_custom', 10);

    function my_project_updated_send_email_custom( $post_ID ) {

        /* new and old field value */
        $dokumenteOld = get_field('field_5ba11346c0289', $post->ID);
        $dokumenteNew =  '';
        if (isset($_POST['acf']['field_5ba11346c0289'])) {
            $dokumenteNew = $_POST['acf']['field_5ba11346c0289'];
        }
        
        /* get elements in array */
        $countOld = count($dokumenteOld);
        $countNew = count($dokumenteNew);
        
    }

Now the problem is that both containt the same number of values when i a add a new line in the repeater field (the new count). I also can see the new value in both arrays.

Sorry, this is the last quesiton i ask i promise. Thank you so much for your help!
