We are using Twitter Photo Cards in our application successfully from past couple of months. But now all of a sudden they are not working intermittently. We have not changed anything in our application (no meta tags etc are changed) but it shows the Photo Cards for some tweets and not for others even when their URL’s are validated successfully on Card Validator.
Please find below one such URL for which validator validates successfully but photo card is not displayed for its corresponding tweet:
Also, sometimes the validator does not validate our URL although all the required tags are verified in green but the image is not displayed. Details of one such tweet:
Could someone please help us understand what are we missing here or if its an issue with Twitter.
