Has anyone noticed a difference in Apple's CNA behavior on iOS 11.0.1? It seems when the user clicks a link whilst still in the captive browser it opens it in the real Safari browser. The problem is the real Safari browser is only found behind the captive browser which takes up the full screen. So the user has to click the blue "Done" link in order to see the URL you linked to. If a user doesn't happen to notice the blue "Done" link they may think the captive portal is just broken or hung.
In iOS 10.3.3 the link would redirect and load the linked page staying inside the captive browser for the duration. Just sharing an observation. Thanks, -- Curtis K.
