My current ICE may be due for replacement after over a decade of use.
I want an EV with NACS that isn't a Tesla. And so I wait. I don't need anything complicated, but I don't want to own a car with the "wrong" kind of port.
To car manufacturers: don't trust Musk. I don't have strong feelings about which connector "wins," I just don't want to be using the one no one else does. And that depresses the value of the car.
I recently added a kasa smart plug using matter. Then the tp-link integration noticed it and forced me to reauthenticate.
That's my closest match to your story.
It had been given my username and password before. But it needed them all over again. I've had that happen for other things before, too.
Not sure if would help or if you have done it... But it takes about a literal minute to do.
