iOS 14.6 not connecting to CARPLAY

My 12Pro is intermittently connecting and disconnecting(mostly). I've tried swapping cables, etc. and it just decides when it wants to connect. Mid Waze, phone call...

I'm in the process of downloading an update for my 2018 KIA Sedona console, and hoping that will work. But, ah man it's a long download/copy process. Anyone have any luck fixing the issue?

It was working last week prior to the iOs update.
