 * Hello [@sudhadev2025](https://wordpress.org/support/users/sudhadev2025/),
 * As the plugin is designed to support older PHP versions for now such warnings
   are not unexpected. Set the PHP reporting to error only, and you will no longer
   see those warning notifications.
 * Best Regards,
 * Simeon Boev
