It's actually to the point that I have stopped using non-browser google search on my phone. In fact I didn't really notice it was AMP just that results from "Ok Google" were annoying as hell after upgrading to Google Assistant. Reading this article was an "oooooooohhhh that's what's going on" reveal to me.
I don't even know where he's getting this "Info" thing. To me it just looks like some sort of chrome window that doesn't let me edit the url. Even when I do "Open in..." to send the link from I guess it's called Amp browser (...that somehow looks like Chrome?) to my browser it leaves me trapped in AMP with weird urls. It's extremely confusing.
I just want to escape to the actual website in an actual browser and for whatever reason I end up having to try and re-find the site in the mobile browser. Maybe there's some obvious way to do this but it's just driving me bonkers.
