I have set summary card with large image a few weeks ago for my website but it does not work.
The tweets provide only short text without any image.
I do not understand why …
My website is whitelisting.
Below the validator result:
INFO: Page fetched successfully
INFO: 17 metatags were found
INFO: twitter:card = summary_large_image tag found
INFO: Card loaded successfully
I checked the robot.txt file, it seems ok too:
My website is: Bio-transition.com
Thank you for support,
