Hi,

 

We develop the Facebook Portal authentication function according to the guidance of Facebook (see the attached picture). Since there has compatibility issue between Apple and Facebook. (Apple product may ask customer to do twice authentication even though customer has passed the authentication in the portal page which pop up by Apple device automatically). According to the Facebook guidance, we disable the captive portal detection of Facebook portal function in Apple products.

 

I'm having the same issue. What i have found is that the iPhone does not redirect if you use a search page. so you have to go to a specific web page (not google) to force the Facebook Authentication to show. As you say this is not very seamless. I'm also having issues when using VLANS over the network as that also fails when using the Facebook Auth. i.e. where the Guest WIFI SSID runs over a different VLAN to the IP of the Access Point. Disabling Facebook Authentication solves the issue thus the problem is the Facebook Authentication.

This is because IOS and facebook are not done well.

 

ios 10 starts to block this kind of  "auto pop up portal", while android is always allowing.

 

you can see that among all omada portal types, only facebook portal cannot pop up automatically on only ios.
