AWS OTA Example Core MQTT Error WiFi Disconnect (CA-314)

[plajarma]

I'm running the demo code provided with esp-aws-iot (mqtt_demo) and after the firmware update is finished, it appears to first disconnect from the wireless access point and then try to close the MQTT connection resulting in error. Is this an issue with the library or are the disconnections done in the wrong order in the example provided? Has anyone else experienced this issue?
