A typical (product) page on my site looks like this
…if (https://www.linkagephoto.com/autumn-at-skaha-9364-1236) is tested in the Twitter Card Validator, the preview looks great with summary and image. Also see “*.linkagephoto.com is whitelisted for summary card” If you click the tweet button at the bottom of the above page however, the tweet includes the page title only, no summary no image.
Any ideas or assistance appreciated.
