How to get rid of the hover zoom in WooCommerce single products

I’m trying to get rid of the function where users can hover over the main product image and zoom into the product. I tried using this code, which has been confirmed by others to work, but nothing changed.

function remove_image_zoom_support() {
    remove_theme_support( 'wc-product-gallery-zoom' );
}
add_action( 'wp', 'remove_image_zoom_support', 100 );

Is this because some other function I’m using is interfering with it?

Here is my functions file:

<?php

add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
function my_theme_enqueue_styles() {

  $parent_style="parent-style"; // This is 'twentyfifteen-style' for the Twenty Fifteen theme.

  wp_enqueue_style( $parent_style, get_template_directory_uri() . '/style.css' );
  wp_enqueue_style( 'child-style',
  get_stylesheet_directory_uri() . '/style.css',
  array( $parent_style ),
  wp_get_theme()->get('Version')
  );
  wp_enqueue_style( 'my-google-fonts', 'http://fonts.googleapis.com/css?family=Lekton', false );

}

//* Redirect archive pages to the home page
function redirect_to_home( $query ){
    if(is_archive() ) {
         wp_redirect( home_url() );
         exit;
     }
}
add_action( 'parse_query', 'redirect_to_home' );

//* Add CPT taxonomy terms to body class
function add_taxonomy_to_single( $classes ) {
  if ( is_single() ) {
    global $post;
    $my_terms = get_the_terms( $post->ID, 'skill' );
    if ( $my_terms && ! is_wp_error( $my_terms ) ) {
      foreach ($my_terms as $term) {
        $classes[] = $term->slug;
      }
    }
  }
  return $classes;
}
add_filter( 'body_class', 'add_taxonomy_to_single' );

//* Add page slug body class
function add_slug_body_class( $classes ) {
  global $post;

  if ( isset( $post ) ) {
    $classes[] = $post->post_type . '-' . $post->post_name;
  }

  return $classes;
}
add_filter( 'body_class', 'add_slug_body_class' );

    if (isset($wp_scripts->registered['jquery']->ver)) {
        $ver = $wp_scripts->registered['jquery']->ver;
    } else {
        $ver="3.4.0";
    }

    wp_deregister_script('jquery');
    wp_register_script('jquery', "//ajax.googleapis.com/ajax/libs/jquery/$ver/jquery.min.js", false, $ver);
}

add_action('init', 'init_remove_support',100);
function init_remove_support(){

}

    return $tabs;
}

//* Add gallery captions for shop items
function gcw_insert_captions( $html, $attachment_id ) {
  $captions="";
  $title = get_post_field( 'post_title', $attachment_id );
  if( !empty( $title ) ) {
    $captions .= '<h3>' . esc_html( $title ) . '</h3>';
  }
  if( !empty( $captions ) ) {
    $captions="<div class="gcw-caption">" . $captions . '</div>';

    $html = preg_replace('~<\/div>$~', $captions . '</div>', $html );
  }
  return $html;
}
add_filter( 'woocommerce_single_product_image_thumbnail_html', 'gcw_insert_captions', 10, 2 );

//* Remove hover zoom
function remove_image_zoom_support() {
  remove_theme_support( 'wc-product-gallery-zoom' );
}
add_action( 'wp', 'remove_image_zoom_support', 100 );

?>

If not, what could be causing this issue?

This is possible using woocommerce_single_product_zoom_enabled dedicated filter hook:

add_filter( 'woocommerce_single_product_zoom_enabled', '__return_false' );

Code goes in functions.php file of your active child theme (or active theme). Tested and work.

It is possible using woocommerce_single_product_zoom_enabled dedicated filter hook.

The hook undocumented available parameters in the options array are:

$zoom_options = array (
    'url' => false,
    'callback' => false,
    'target' => false,
    'duration' => 120, // Transition in milli seconds (default is 120)
    'on' => 'mouseover', // other options: grab, click, toggle (default is mouseover)
    'touch' => true, // enables a touch fallback
    'onZoomIn' => false,
    'onZoomOut' => false,
    'magnify' => 1, // Zoom magnification: (default is 1  |  float number between 0 and 1)
);

add_filter( 'woocommerce_single_product_zoom_options', 'custom_single_product_zoom_options', 10, 3 );
function custom_single_product_zoom_options( $zoom_options ) {
    // Disable zoom magnify:
    $zoom_options['magnify'] = 0;

    return $zoom_options;
}

add_filter( 'woocommerce_single_product_zoom_options', 'custom_single_product_zoom_options', 10, 3 );
function custom_single_product_zoom_options( $zoom_options ) {
    // Changing the zoom event option:
    $zoom_options['on'] = 'click';

    return $zoom_options;
}
