I saw this on a Reddit blog. I've got no idea as to the accuracy, but it would explain things. (Posted by “duke_of_alinor”.)
I happened to be over at the factory to charge and buy a hat for a friend so I asked at the factory showroom. Tech came from the back and rather sheepishly said:
"It's a bug in V9. We changed the billing and had to take everyone off free supercharging then put them back on. Might take 3 days for the system to catch up with the changes. Sorry for the inconvenience". Further questions only got "just wait a while, if everyone asks it will take even longer". I thanked him for his candor.
