I can't seem to get the thumbnail preview to change when I send the link to my campaign landing page. If I send the link via text message, it looks pretty much how I want it. But when I send the link via Facebook Messenger (the primary method) it sends some other thumbnail that I don't use anymore. And no matter how many times I change the logo on both the landing page AND on my account, the thumbnail sent through FB stays the same.
And also, can I edit what it says at the bottom instead of saying just "Sign up"?
This is what it sends through Facebook.
Finding the answer to your question took me on quite the journey! Thanks to your inquiry we are now tracking the request to have control over that thumbnail image. This will take some time to investigate, but in the meantime I recommend using a Social Post to share your landing page on social media.
The best part about this is you get a full preview before publishing the post!
