丰富的评论摘要未显示

Question

过去 2 个月我一直在努力使评论摘要有效。有一次我会谷歌它并查看我的星星，但现在它又无缘无故地消失了，因为我没有做任何改变。 我还设置了规范标签。 代码：

<script type = "application/ld+json">
        {
        "@context":"http://schema.org/",
        "mainEntityOfPage":{
           "@type":"WebPage",
           "@id":"https://androidshark.com/traffic-racer.html"
        },
        "image":"https://androidshark.com/img/icons/trafficRacer22.jpg",
        "url":"https://androidshark.com/traffic-racer.html",
        "description":"It’s not everyone’s cup of tea, but if you enjoy mobile games like these then this is one of the finer experiences the free side of the Play Store offers.",
        "@type":"Product",
        "name":"Traffic Racer Review",
        "review":{
           "@type":"Review",
           "datePublished":"2020-12-17T00:44:16.000Z",
           "headline":"Traffic Racer Review - Android Shark",
           "publisher":{
              "@type":"Organization",
              "name":"Android Shark",
              "logo":{
                 "@type":"ImageObject",
                 "url":"https://androidshark.com/img/razLogo.png"
              }
           },
           "author":{
              "@type":"Person",
              "name":"Spike"
           },
    
           "reviewRating":{
              "@type":"Rating",
              "ratingValue":7,
              "worstRating":0,
              "bestRating":10
           }
        }
     }
    </script>

我还多次重新索引此页面，并使用适当的 robots.txt 文件更新了站点地图。

这 5 个警告是可选的，例如“aggregateRating”，因为这是一个评论家评论网站。 在这一点上，我不知道该怎么做。任何帮助将不胜感激。
