Hi Bill. I can't understand you more. I'm bit more experienced now. It looks that Taycan is very sensitive how the charging connector is connected to the car. You have to hold it until the car locks the connector and the indicator flashes white. Ionity even has a video showing it: .
I was facing the same problem during my road trip to France this weekend with brand new Taycan. I've learned from another discussion that park brake has to be activated to start the charging.
