Hi @Undrumen,
Thanks for reaching out.
Out theme is Woocommerce compliant, but I agree there are ways to implement it. It just happens their codes are dependent on those other filters that aren’t available once woocommerce_content() is invoked. Please check this https://docs.woocommerce.com/document/woocommerce-theme-developer-handbook/
With that, all hooks are handled by Woocommerce within woocommerce_content() that’s why you can’t find woocommerce_show_page_title within our theme.
It’s also said that you have to create your own taxonomy template, which in this case, within the child theme. That way, you could use the filters you wish to add.
Our theme integration for Woocommerce is only based on that integration. You can confirm that by editing the file wp-content\themes\x\framework\views\{YOUR ACTIVE STACK}\woocommerce.php and other related files.
Though I can’t really provide any answer about the 3rd party plugin, I’m also not fully familiar with the said plugin. It may need different or multiple integrations instead of just relying on single woocommerce_show_page_title hook.
Thanks!
