I charged my Model X for the first time away from home at a free level 2 charger at the mall yesterday. When I got back to my car, the charging cycle was complete (full to 90%) and I was trying to figure out how to release the charging plug and SAE J1772 adapter. Everything I read online says that you should see an "unlock charging port" button on the charge screen upper right corner, but my "charging complete" screen didn't have a button. I had to change the charge limit slider so charging would start again to get the charge port unlock button. Has anyone else observed this? Does the keyfob "open charger door" button press unlock the charge port too? Sorry for the noob question.
