Hi. The problem is that the SNAP always uses the same image on Facebook. He has reviewed his whole life and tried with different options, and he works 1 or 2 posts and then repeats the image again. The truth is I’m confused. If someone can help me or if this is the same, I would appreciate advice. regards
SNAP does not set or control what info (image, title and description) is used in the “Web preview” part of the shared post.
Facebook (LinkedIn, Google+, Twitter, Telegram, Vk.com, etc…) is setting this info by itself, using Open Graph (OG) metatags from your site. Please set them correctly. They must be set at the time of autoposting.
