Do not show star reviews on the Google search results page

Hi everybody. I am having a problem looking forward to help. My website was https://uocmotulang.vn before I updated the latest version of WordPress today. So on the Google search engine, my website still shows star reviews in search results. But when I updated WordPress to the latest version. The star rating on the search results page is gone. Please help me show me back my star rating on Google search results. Thank you!
