When you share a Url from any Google product, it creates a share.google minify Url. When iMessage fetch the Url meta headers, it receives the og:title, og:url, og:site_name, og:image. But it only show the preview card with og:image, og:title, and og:site_name, ignoring the value of og:description.

I currently have a custom UITextView that properly changes the color of a link to the custom color I have set, however, when I click and hold the link, and the animation plays that makes the link bigger and creates a boarder around the link before previewing the website, the link changes briefly back to the system default color, and when letting go, it changes back to my custom color. Is there anyway to have the link always be my custom color, even when clicking and holding?
