I don’t understand how heating with auto is supposed to work.

2023 S60. It basically never gets warm. The front vents next to the screen blow no air at all. The front vents on the edges below the tiniest possible bit of air. The vent near the windshield ramps up and down partially dependent on if I'm driving or stopped, but also seems very random for the most part. It sounds like a jet engine, and I don't get any air anywhere else. When I turn off auto, everything works as I expect. With all the vents blowing the expected amount of air.

The Volvo dealership told me that it's working as expected. I can't imagine that this would be designed this way.
