jlv1, did you happen to notice if your car had "internet access" while at Sunday River?
I have been there 3 times this season and could never use the app to make sure it was charging OK.
When driving home yesterday, I did not have LTE service until I got to Paris, Maine about 25 miles away.
The previous 2 seasons I remember having things working properly since I could interrogate the car from the ski lodge.
Nope, the car had no LTE at the resort; like you we did not get it back until around Paris.
And because of that... I stupidly managed to lock myself out of the car.

We were going to be there all weekend so I charged overnight starting Friday. First thing 7AM Saturday I went to go get the car. It had snowed 5" overnight so I had to clean it off. And since it was 15°F that morning, I thought I'd leave the heat running while cleaning off the car. Since I knew it would stop running the heat when I closed the door, I left the fob on the front seat.
It wasn't until I had finished cleaning off the car 5 minutes later that I realized it had locked itself with the fob inside. And without access, I couldn't unlock it from my phone. Really dumb of me.
Thankfully my wife had her fob, but up at the Jordon Hotel. She had to hop on the shuttle and come rescue me.
FWIW, the other two destination chargers were in use overnight, so I felt good freeing up a space first thing in the morning for anyone arriving during the day. But it also meant that they were able to use them without an issue (whereas I couldn't). I'm bringing the car in for service next week to have the charge port looked at.
