DO NOT, I repeat do not place that parchment paper in your Air Fryer while it's pre-heating ...
I started to smell something - BURNING -
Ya learn something new every day ...
I guess, that because I have the oven type a/f, I've never used parchment paper as it was pre-heating.
I always have whatever I'm cooking, on parchment paper, on a tray or in the basket, outside the a/f as it heats.
That could be scary.
