iOS devices are failing to launch WebSheet (i.e. captive portal mini browser) when auto-join is used to connect to Hotspot 2.0 SSID with a captive portal. Logs captured from the device & RADIUS show that the device associates to the SSID, but does not launch the WebSheet due to the error, "Unable to launch WebSheet because this network has become captive". Afterwards the device may send an EAPOL Logoff request to the Access Point & disconnect from the network. If manually selecting the SSID from Settings > Wi-Fi, then the same device will log It's a manual join so no further checks required, remain associated to the SSID & launch the captive portal browser which is able to load the captive browser. info 17:28:35.298531-0500 configd device setup is completed info 17:28:35.298566-0500 configd Unable to launch WebSheet because this network has become captive, blacklisting network [HS2_Captive_Test] info 17:28:35.298604-0500 configd Removing FF981347-FDFA-45FD-82D9-88BA0426C0A3 default 17:28:35.298641-0500 configd __BUILTIN__: PresentUI result Temporary Failure (6) default 17:28:35.298677-0500 configd CNPluginHandler en0: Failure (__BUILTIN__) default 17:28:35.298716-0500 configd Temporarily disabling (blacklisting) HS2_Captive_Test Websheet should only be launched when the device is captive.
