All seemed to be working well last night. Tried the various screens including service screens. I had graphed a charge session for about 15 minutes or so. I saved the .csv, shut everything down, including closing the app. I downloaded the .csv via iTunes on my Mac.
This morning I got in the car and started the app. It came up briefly but there seemed to be a flash and I was returned to the iPhone home screen. I tapped the icon again and the same thing happened. I thought the app had crashed but it was still actually running in the background. I selected it from the running apps instead of the app icon, and it came up.
Most things seemed to be working, but the graph would not update. It is still showing last night's charge recording. Not sure how to erase the graph and start with a new one, or at least continue graphing new values. I see options in the settings pertaining to reset "manually","automatically", "drive and charge", etc... But I tried the different ones, turning the car on and off and the old graph remains and doesn't update. I left the app running as I drove this morning but the old graph remains unchanged. The text info on that screen does update the SOC and GIDs...
Now that I am not connected to the WiFi, I can close the app and restart it from the icon just fine.
I noticed you're still working with polymers.
