Not user friendly

The plugin it installs smoothly but it is very difficult to do settings.
It should be more intuitive and easy to set.
Author website is currently not configured properly in https so it doesn’t show images. The documentation is really poor.
It is ok if you want to use it for a blog but it is very limited to use for a business.
Example in schema.org :

<script type="application/ld+json">

  "@context": "https://schema.org/",
  "@type": "Service",
  "serviceType": "Weekly home cleaning",
  "provider": {
    "@type": "LocalBusiness",

  },
  "areaServed": {
    "@type": "State",
    "name": "Massachusetts"
  },
  "hasOfferCatalog": {
    "@type": "OfferCatalog",
    "name": "Cleaning services",
    "itemListElement": [
      {

        "itemListElement": [
          {
            "@type": "Offer",
            "itemOffered": {

            }
          },

            }
          }
        ]
      },
      {
        "@type": "OfferCatalog",
        "name": "One-time services",
        "itemListElement": [

          },
          {

            "itemOffered": {
              "@type": "Service",
