丰富的评论摘要未显示

如何解决丰富的评论摘要未显示

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。
