I had the other kind of CarPlay connection issue again this morning on 2.1.52. I walked away from the car for a minute while it was still on (left the door cracked open to keep it alive), walked back, and CarPlay had disconnected. No big deal, I walked out of range, so I gave it a minute. No auto-reconnect. I pushed the CarPlay connect button in the car's settings, it spun for a minute, I gave up. I turned off bluetooth on my phone and the car, turned them back on. That usually sorts it out. Still no connection. I ended up just closing the door and walking away again, then coming back. CarPlay immediately connected.
