To follow up on this one, over the last few months I even went so far as having "A full OnStar subscription".
tldr; Same experience all these months later. I finally activated Autocharge+ on EVgo directly (bypassing the myChevy brand app) and it worked.
tldr; tldr; The Chevy app on Android continues to suck. I just deactivated OnStar and am refocusing my time contributing more BoltEV patches to
OVMS.
Added some charging state + graphics code today...
OVMS DCFC Charging:
OVMS AC Charging:
OVMS App. Car plugged in and charging via AC...
It ain't pretty, but conveys state better.
