Hello,
We will add some improvements in the next update and all that you will need to make will be adding the next snippet in your child-theme/functions.php
add_filter('single_product_main_gallery_speed', function() { return 2000; }); // 2000ms or another value
Example: https://gyazo.com/07de9f4c6134db7feefd5d2c5f1c5876 The next update will be released within the next 2 days.
Regards
