Quick Summary: I can only remove the Adapter+Charge Plug if I first remove the J1772 then the adapter. Last night I charged our new M3 to 62% with our home EVSE (this one) . I plugged the adapter into the J1772 and plugged it into the car. Charging was complete in the morning. I couldn't pull out the combined plug plus adapter. In the car, if I selected unlock charge port, I'd hear it unlock then immediately relock. I eventually got it out by first unplugging the J1772, then unlocking, then removing the adapter. Is it supposed to work that way? Why did it immediately lock again after unlocking? Thanks.
