We operate a captive portal WIFI network in a walled-garden setup. There is no public internet access on this network. Users connect to our SSID and can only reach a local resource. On Android, our captive portal can show a button that launches the devices default browser and navigates to our portal page. We cannot reproduce this on iOS: we can place the button inside the CNA tear sheet but tapping it does not open Safari, the redirect simply does not happen. I found this older thread describing the same need: https://developer.apple.com/forums/thread/75498 From that thread, it seems the behavior changed several times. It reportedly worked around iOS 11.2 then broke again in later releases. My questions: On current iOS, is it possible to open Safarı or the default browser programmatically from within the CNA? For example, via a link or button after authentication? If yes, what is the supported way? If it is not supported, is that intentional? Is there any official documentation describing CNA limitations and the recommended pattern? For a walled-garden network with no public Internet, what is Apple's recommended approach to move the user from the CNA into a full browser session?
