If you’ve recently updated your description, Google might not have crawled the page, or updated their index with your content. It can take time for Google to process the changes you made, depending on how frequently your website is crawled.
You can ask Google to recrawl your URLs when changes are made to any page on your website. Please note that requesting a crawl does not guarantee that inclusion in search results will happen instantly or even at all. Google systems prioritize the fast inclusion of high quality, useful content.
Follow the guide here to request a crawl of individual URLs.
