Hi everyone, I have a new issue, may be someone can help here.

Hello Drupal developers. I have a problem, has to do with image size, Google Accelerated Mobile Pages (AMP) and Google Carousel for Top News. After upgrading from Drupal 7 to Drupal in in July, my website basically stopped appearing for Latest from Torque News as AMP pages when searching Torque News (my site). It stopped sending me AMP traffic, although AMP pages validate well. May be the problem has to do with image size. I am using Google required 16x9 ratio with minimum 1200 size, using 1200x675 size, which has worked great in the past Drupal 7. Now a few days ago I noticed that when I paste my articles (Example https://www.torquenews.com/14335/tesla-model-x-demand-increasing) to our Telegram page, it shows a very small size image (we don't have that size image style), but when I paste another successful site's article to our Telegram, it shows the right full size. My question: What am I doing wrong? Can you please look at the source code and tell me why Google and other search engines see the small size image and not the full size image. See the example in the attached screenshot from our Telegram. Our sample AMP page is https://www.torquenews.com/14335/tesla-model-x-demand-increasing/amp Thank you.
