Not sure if this has happened to anyone, but when I go to unplug my car, I don’t get the light blue light right away. Instead, it takes a second for it to turn light blue and if you don’t remove it IMMEDIATELY it locks the charging cable again. So I have to tug on it steadily so that when the light turns light blue I can unplug it quickly. I tried to show my wife but then it acted normally but I think that was the only time it worked properly.
