Behavioral change in iOS 18 related to SCEP profile downloads from the browser.

Hi Team,

We have noticed a behavioral change in iOS 18 related to SCEP profile downloads from the browser. In current flow, we are using Cisco ISE as SCEP server. While testing in iOS 18, we have observed that before communicating to SCEP server iOS is asking to download the SCEP server certificate. This differs from iOS 17.4, where the communication happens seamlessly without any new prompts.

Could you please confirm if this certificate download popup behavior is expected in iOS 18? Additionally, we would appreciate any guidance on whether this change in likely to persist in future updates, as it impacts our user flow.

Please let us know where we can attach video recordings of previous and current processes.

Thanks

One more point to mention here is, certificate download prompt is coming for third party CA as well.
