The latest ESP32 Arduino Core (1.0.6 and above) requires a call to SecureWiFiClient.setCACert() for TLS/SSL connections. The secure wifi client in previous versions didn’t require this function to be called in order to establish a connection with Adafruit IO's MQTT server.
This pull request updates the AdafruitIO_ESP32. wifi adapter files to include the root certificate and updated code.
