The reported issue occurred after updating certain iOS devices to a newer iOS version, where the captive portal page failed to display properly.

Troubleshooting Steps That Helped Resolve the Issue:

1. Remove the saved Wi-Fi profile from the affected iPhones.
2. Reconnect to the SSID to ensure the device refreshes its network settings.
3. On the Nebula platform, verify that the SSID associated with the captive portal is properly configured.

These actions help ensure the iOS device correctly triggers the captive portal page after the system update.
