Compatibility Notes

Themes: This plugin works with most WordPress themes that utilize the standard comments_template() function. If your theme uses a custom, non-standard comment system, visibility restrictions may require additional configuration.
Caching: If you use server-side caching (like Varnish) or caching plugins (like WP Rocket), ensure that the comment section is not cached for logged-in users to prevent unauthorized users from seeing cached private comments.
