Do you fix bugs that appeared after a WooCommerce or WordPress update?

Yes, post-update breakage is the most common ticket we get. WooCommerce core updates, a PHP version bump, or a plugin auto-update can break a theme hook, a custom snippet, or another plugin. We bisect to find exactly what the update changed, then update your code to be compatible, so you stay on the secure, current version instead of being stuck on an old one. This is the same work covered on our WordPress bug fixing page for non-Woo sites.
