Links sharing is also less predictable. What will the shared message look like? Will it contain useful context like the page title or will it be a giant unreadable URL? Will there be a link preview? Depends on the messaging platform (SMS and Signal no, iMessage and Slack yes). Will it even take the user to the same page? Will there be a paywall or a redirect to an infinite scroll?

A screenshot is truly WYSIWYG and is the most reliable way to know that they will see the exact same thing that you see.
