As part of Facebook's efforts to limit the amount of fake news on its platform, they have decided to remove the ability to customize link previews (i.e. headline, description or image) when publishing posts.
According to Facebook: "Allowing modification of link headlines and images when sharing posts has provided a potential vehicle for malicious users to misrepresent underlying link content, and hence why Facebook is removing the capability."
When did this come into effect?
Facebook released this change to for all third parties like Sendible in July, 2017.
How does this affect your posts from Sendible?
Facebook will now automatically generate the link preview on its platform and will no longer give you any control over the appearance of the link preview before posting.
Are there any workarounds?
Whilst we appreciate it's not the most ideal solution, the only option we can provide in this case if the domain you're linking to has not been verified by Facebook is to replace the link preview with an image of your choice.
You will be able to source the image from the chosen URL and choose to attach it. The shortened link will be included in the body of the post.
