Called Support and they were able to tell me the car went into sleep mode about 4 hrs ago and 4.2 never made it to the car ("It got stuck"). Tech thought this was a bug in 4.1 that caused it to sleep even though it wasn't supposed to.
Guess I will be app-less until I get back to her on Friday morning. Damn I am spoiled by this car!
Update:
So now, after going off the grid for 24 hrs, I was able to connect with the app again this morning. It looks like the car woke up and phoned home? Even Tesla thought I wouldn't be able to connect until I manually woke the computer up by opening the door when I got home.
Wish I understood the logic behind this.
