Interesting, I've had issues with the update with my carplay. This is in a 2017 Ford F-250 with Sync 3. On Tuesday I had taken a conference call (using an app called Zoom which is a Webex competitor), and everything was going fine. Then I got a phone call and the display switched over to the phone and I hit decline, expecting to be put back in the meeting. The phone did put me back in the meeting, but it also fired up my Pandora and started blaring that over my conference call. I had to kill Pandora to fix it, but then it started sending massive feedback even though I was on Mute. I eventually rebooted my phone and took the call via dial-in.
