I've tried just about everything for every developer update buy Bluetooth carplay is not working.
HOWEVER, I screwed around with Wi-Fi connection to my car and Carplay is working. I didn't test much but maps did come up as well as come choppy audio form Instagram. So, connected to my Hondas WiFi, the "Connect" button changes to CarPlay and something is working again!
