Warming the cabin while plugged in

[SrDeVo]

My Equinox EV will warm the cabin when NOT plugged in but not while it's plugged in, WHY?

I would suspect many systems would not be available during charging, to speed up the charge rate. I don't have an EV, so this is just a guess. check the manual or with the dealer, hopefully you'll find the answer.
