I bought an Ideafab 14-30 adapter for out 2017 Volt's factory charger, but it appears to have not changed the charge rate. The adapter I got is a 14-50 with the curved pin. When we had our Tesla we used a 14-30 adapter with the L-shaped pin and it definitely charged at 220v. Is it possible there is no power going to that curved pin in my outlet? I did request a 14-30 adapter because the circuit is only 30A but received this 14-50 plug instead for some reason. I've attached a pic of the charge screen.
