Detect incorrect password - no event is raised, but it used to be

[jcsbanks]

No event is raised when an incorrect password is entered on attempting to join the ESP32 AP. ESP-IDF v3.3-beta1-506-gebdcbe8c6. Some time in the past this did produce SYSTEM_EVENT_AP_STACONNECTED followed by SYSTEM_EVENT_AP_STADISCONNECTED which I detected in the event handler to give the opportunity to use a magnet that is detected by the ESP32 hall sensor as a physical password reset, but it was lost in an update to esp-idf.

I have a working event handler that displays many events but also the number if one is not recognised:

{
	static char tag[] = "app_main";
	static int nextStatus = 0;
    switch(event->event_id)
    {
        case SYSTEM_EVENT_WIFI_READY:
        {
           ESP_LOGI(tag, "SYSTEM_EVENT_WIFI_READY");
           break;
        }
  
        case SYSTEM_EVENT_SCAN_DONE:

        }
  
	case SYSTEM_EVENT_STA_START:
        {
           ESP_LOGI(tag, "SYSTEM_EVENT_STA_START");
           ESP_ERROR_CHECK( esp_wifi_connect() );

           ESP_LOGI(tag, "SYSTEM_EVENT_AP_STADISCONNECTED");

				printf("Disconnect without IP assigned - wrong password? Starting magnet scan...\n");
				nextStatus = 0;
				xTaskCreate(task_magnet, "magnet", 2048, NULL, 5, NULL);

           break;
        }

        case SYSTEM_EVENT_AP_STAIPASSIGNED:

		   nextStatus = 0;
           break;
        }
		
        case SYSTEM_EVENT_STA_DISCONNECTED:
        {

           break;
        }
  
        case SYSTEM_EVENT_STA_AUTHMODE_CHANGE:
        {
           ESP_LOGI(tag, "SYSTEM_EVENT_STA_AUTHMODE_CHANGE");

           break;

        case SYSTEM_EVENT_STA_LOST_IP:
        {
           ESP_LOGI(tag, "SYSTEM_EVENT_STA_LOST_IP");
           break;
        }
  
        default:
        {
           ESP_LOGI(tag, "EventHandler received %i", event->event_id);
           break;
        }
	}
    return ESP_OK; 
}

The only output I see in monitor is white text like this, but it appears invisible to my application?
