I wonder how the link preview will work on mobile. In the past, click and hold on a partially obscured URL on mobile basically worked like "hover" on the desktop and revealed the whole link (useful to see if the link was malicious, or had click tracking, or just didn't go to the site you thought it did).
I hope there's still a way to do that feature. If nothing else, by disabling the preview which I doubt I would find as useful.
edit just retested on mobile. click and hold is basically the context menu. If you tap on the first item in the context menu (the link ended in …) you get the full link wrapped.
So, more correct to say that click and hold is the right click context menu on mobile, even though I mostly just used it for that display whole link feature. Perhaps they could put the preview as a sub item of the context menu.
