Try this: keep the Kia Connect app open on your phone. In your car, go to the Home screen, then Kia Connect, Settings, and Reconfigure. Next, close the app on your phone and reopen it.
FYI, V2L is only for powering devices outside the car, not for charging the car battery. Making a cable to connect 2 male plugs is hazardous and won't function.
