Hi, I have a project to deploy captive portal for public internet access. With all the other devices is working fine (PC/Android/Ipad/Mac) except for IOS devices.
IOS devices takes around 45 seconds to show the Captive Network Assistant (mini browser).
I am attempting to use the new captive network DHCP advertisement in option 114 as described here: https://developer.apple.com/news/?id=q78sq5rv to reduced this delay.
But It appears that in the first attempt it uses the old method and makes an GET to http://captive.apple.com/hotspot-detect.html. However, if I rejoin the same network a second time (without forgetting the network inbetween) it uses the new DHCP option 114 and opens the captive portal as described in https://developer.apple.com/news/?id=q78sq5rv.
Any idea o what is happening?
