They load fine (and FAST) for me, that's never been an issue.
But because they have a completely different scroll weight the feel wrong. I can't easily share them, and the stupid bar at the top of the page takes up 15-20% of my screen.
They're obnoxious to interact with. If they fixed just two of those issues (make the bar tiny, don't mess with scroll feel) I'd be a lot happier. As it is I find myself actively avoiding AMP links in Google, but as the become more prevalent I wonder if I'll have to switch to some other search engine on iOS.
Apple chooses to use accelerated scroll for iframes in mobile safari for some reason. The inner iframe is needed in AMP for security reasons since the experience on google includes third party iframes as part of the rendering of the article.
Google has fixed it so the site name header finally goes away when scrolling.
AMP adds an additional horizontal bar on the page, under the native address bar, clobbering valuable screen real estate on a mobile browser. Why anyone thought this was a good implementation and ready for prime time is beyond me.
They don't load. Ever. 100% of the AMP links I've tapped in Safari on 10.2 just show the AMP header with a blank page beneath it. I don't have an ad blocker installed on my phone, or anything else that should be screwing with it to the best of my knowledge.
I'm on iOS 10.2 also. Searching for something like "site:reddit.com casserole" gives a couple of AMP results. Clicking them just shows google loading circle thingy indefinitely, the page never opens.
I just did this on my iPhone, and it worked instantly. In fact I've never seen an AMP page that doesn't load...
My guess would be that you have a content blocker, ad blocker, anonymizing proxy, DNS server with ad-blocking, or something in your setup that's breaking it, because it's not broken natively.
