Every Jotform link shares Jotform's ad, not your form
og:image on every form.jotform.com link is Jotform's own homepage image. Your form isn't on it.
So your customer gets Jotform's ad in Messages
The form has a name, a purpose, and a business behind it. The card shows none of that.
What's actually wrong
Load any form on form.jotform.com and read the tags. og:title is the form's name. og:description is the same sentence on every form, "Please click the link to complete this form." And og:image is Jotform's own marketing image, the one on jotform.com's homepage. There is no twitter:card at all. So when someone texts a customer a link to their intake form, the customer sees an ad for Jotform. The documented fix is to upload a logo to the form, which then becomes a small thumbnail. Most people never do, so most forms share the ad.
This is problem 3 of the 5 ways link previews break. The full breakdown covers the manual fix and the automatic one.

The ask looks like spam
A link that says "Please click the link to complete this form" over a stranger's logo is what phishing looks like. People hesitate before they tap, and some never do.
The business disappears
The form belongs to a clinic, a school, a contractor. The card belongs to Jotform. Every share is a missed chance for the business to look like itself.
Support keeps answering the same question
"How can I customize the thumbnail that appears when Jotform link is shared?" has been asked in Jotform's support forum for years, and the answer is a manual logo upload that most users never find.
The form, as a card
Rendered from the form itself, so the business and the ask are the first thing people see.
The same form, everywhere it gets sent
Slack for the team, WhatsApp for the customer. One ad today. Here's what the card could carry instead.
The same form in Slack
The link a coordinator drops in the team channel.
The same contact form on WhatsApp
Where small businesses actually send their forms.
For whoever owns the templates
The image is the homepage ad
form.jotform.com serves the same og:image as jotform.com. It was never meant for a customer's form; it was meant to sell Jotform.
og:image → cdn.jotfor.ms/assets/img/landing/opengraph.pngThe manual fix is a logo, not a card
Jotform's answer is "add your logo to the form." That yields a small square thumbnail and depends on every user finding the setting.
One tag on form.jotform.com fixes every form
OpenGraph+ renders the card from the form itself. Jotform adds one meta tag once, and every customer's form shares as that customer's form.
