I am new to twitter tags. I applied "Summary Card with Large Image" card type to share the blog. All the required tags applied on our website. But whenever a new blog comes, every time we need to validate the blog URL to show the content and images while posting on the twitter. If I don't validate the URL, then it only tweets the URL.
URL affected: https://www.savingsforseniors.com/blog/blog-for-test
Please check the URL, I didn't validate this URL. All the other blogs are validated and working fine.
For validation, I am using this link:https://cards-dev.twitter.com/validator.
