Captive Network Assistant

Has anyone noticed that after connecting to a captive portal with an iPhone running IOS 8, there sometimes is a delay with Apples captive network assistant displaying the "Done " option. This delay seems somewhat random but when it happens "Cancel" is the only option then after about 30 seconds "Done" is finally displayed. I know that you can disable CNA on the controllers captive portal configuration but this also preventst the splash page from automatically poping up when connecting. The user must then open a browser to recieve the splash page after it times out several hours later, but if they are trying to use an App, it isn't obvious that they need re-accpet via the splash page. 

 

Is there a way to setup the splash page so that once accepted it is never displayed again? It seems that the max timeout is about 4 hours or so.

 

I would greatly appreciate any help with this issue and I have attached an example of the CNA in it's delayed condition.

Unfortunately that is an IOS issue and the only option you have is to either disable CNA or leave it as is.
Thank You,

You're running into an issue that's addressed at https://arubanetworkskb.secure.force.com/pkb/articles/HowTo/R-1680

and http://community.arubanetworks.com/t5/Controller-Based-WLANs/What-config-on-Aruba-is-needed-to-Bypass-Apple-Captive-Network/ta-p/170040

Unfortunately some of the information in the above seems to be outdated or not directly relevant to Aruba Instant. Or it may prevent the delay (good) but disable a useful Apple feature (bad).
