Steps to reproduce:

  1. Open captive network (DHCP + DNS → portal, hotspot-detect.html returns 302).
  2. Scan the Wi-Fi QR code with Camera and tap "Join".
  3. Stay in Camera.

Expected: CNA is presented after a Camera-initiated join, as it is after a join from Settings > Wi-Fi. Actual: CNA is not presented until the user manually opens Settings > Wi-Fi.

Impact: In-flight Wi-Fi with no internet, where the portal is mandatory. QR codes are the only onboarding method, and most users stay in Camera.

Environment: iOS 18.7, iPhone 15 Pro max

Questions:

  1. Is there any supported way to have the CNA presented after a Camera-initiated Wi-Fi join, without requiring the user to open Settings or Safari?
  2. If not, is this expected behavior, or a bug worth tracking?
