Yeah, only had my Bolt a few days, but it's been spotty for me..
I've never had any errors, but sometimes after the update finishes, it's just the same data..
This morning, I got up and checked to make sure my charge worked. Refreshed, and no change (no errors, just no change in the data).
Did that 2 more times, no change..
Went downstairs and into the garage to check the car..
Fully charged..
Drive to work, updated again. Worked this time... (i.e. showed new range that looks about right considering my drive in..)
I'm just assuming that the update from car to servers is what isn't happening, and phone to servers is because I'm not getting errors.
The Leaf App was buggy too, but it seemed to do a better job of letting me know that the error was car to server. Also, it included an update date/time, so I could tell if my last update was actually recent.
Hopefully it stabilizes over time..
