Hi osherezra3363
nofollow attribute in “Add to Wishlist” button is used to avoid bot indexing ulrs as https://yoursite.com/?add-to-wishlist=12345
These urls, used by Wishlist to add a product in the list when js is disabled, should not be indexed by bots, and for this reason we added a nofollow attribute
If you really want to remove these attributes, anyway, you could overwrite add-to-wishlist.php and add-to-wishlist-button.php templates, copying them from wp-content/plugins/yith-woocommerce-wishlist/templates/ and pasting them under wp-content/themes/<your theme or child dir>/woocommerce
Then you can edit your brand new template, and remove all rel nofollow from there
Hope this helps you
Have a nice day
