Removing Quantity (+ and -) from product page

Hello!

I’m just wondering if Site Origin (Unwind) theme is over-riding Woocommerce and keeping the + and – quantity buttons on product pages? For the products in question, under the product settings, I’ve tried selecting “Sold Individually – Enable this to only allow one of this item to be bought in a single order”. This removes the text input, but not the + and – buttons.

I’ve tried the following code:

/**
* @desc Remove in all product type
*/
function wc_remove_all_quantity_fields( $return, $product ) {
return true;
}
add_filter( ‘woocommerce_is_sold_individually’, ‘wc_remove_all_quantity_fields’, 10, 2 );

as a snippet, however again it removes the quantity text input, but the increase/decrease quantity buttons remain. Is there something about the theme keeping those buttons? And any tips on how to remove them?

Thanks for any advice!
