So I had a Model S and it turns out the charge port works differently in the X. I feel like every week there is a new surprise. Anyway, so I brought the car in for service for among other things to fix the charge port because it didn't work by pushing the cord button. Turns out the cord button doesn't open the charge port on the X. It opens manually by just simply pushing it. Why they have a button on the cord I'll never know... Maybe the X doesn't have its own cord yet? Anyway, I learned that but I also discovered if you push and hold the trunk of the key fob it also opens the charge port. Anyway, in case anyone was confused, I thought I would share my discovery...
