Doesn’t work with plus/minus buttons

The plugin doesn’t work together with any of the most popular plugins that add buttons to change quantity. I have tried:
https://www.ads-software.com/plugins/wc-quantity-plus-minus-button/
https://www.ads-software.com/plugins/smntcs-woocommerce-quantity-buttons/

Maybe it’s not an easy fix, but at least I wanted you to know about it (you may consider it a feature request). Your plugin still works, but the buttons from the other plugins simply don’t show up.
