IAP Captive portal for Guest isn't auto pop-up once connected to guest SSID

[Michael_Clarke]

Any particular device type this is happening to?

Are you using the internal portal or an external one like Clearpass?

Hi,

No Clearpass, Its Aruba central managed IAPs.

When we use Apple devices connecting to Guess SSID, the Login page for Portal is not coming out imediately, only redirect if manually open the browser.

Thanks,

Akram.

Sorry, I don't have much experience with Central.  Hopefully someone else can comment though.
