I've watched a video of a tumble dryer being torn down and repaired on youtube, where the previous owner had used dryer sheets, the stuff from the sheets had run down inside the case and had also coated the conductivity sensing wires so autodry didn't work properly until they were cleaned up.
Personally, I'd rather my laundry wasn't scented. I do use fabric conditioner, to deal with static and improve softness, but choose a lesser scented one. That said I use to find the scent left by the detergent I currently use due to it being regularly discounted, rather overpowering, but having lost most of my sense of smell since covid, I no longer notice it.
