"Your browser is currently unsupported" BYOD portal - ISE 2.4 U14

[phake]

We've been noticing that any new iOS device trying to use and enroll in our BYOD portal/setup, they're getting: "Your browser is currently unsupported". 
I'm fairly confident it's any device that's upgraded to iOS 15, 15.1, 15.2. It was working on several older test iPhones last week. 
I have: 

Version: 2.4.0.357
Installed Patches: 5,8,9,14

Any thoughts on how to get this running again?

Seeing this as well on 3.1.0.518 patch 3.  Captive portal bypass is not working in my environment; possibly because I am using a Meraki cloud controller instead of Cisco WLC.

This thread is from 2.4.  I would suggest creating a new one for your issue.

I'm seeing the same result - sometimes, however it's a very long timeout and not really a suitable work-around to provide to customers.

3.1p4 and 3.1p5 both with same issue.

Hello Everyone,

Did anyone resolve the issue?

I encounter same issue with ISE v3.2patch 4 and using WLC 3500 v8.10
