Having issues displaying images in Twitter cards from one of our websites. The images are above the minimum dimensions, smaller that 1MB, and unique to that page. Open Graph images are set. Our developers have double checked the metadata tag configuration and say everything is in place. However, sometimes the image displays, and sometimes it doesn’t:
Furthermore, I’ve found instances where the thumbnail appears without issue in the Twitter Card, despite it being an image used elsewhere on the website and it is not set as an open graph image on this particular page.
Thanks for your help!
