So on Kerry’s orders and to help out @Smithy, I tried reheating some fries in the CSO. Bearing in mind that these were not the best fries to begin with I believe I brought them back to their less than perfect state by re-heating them for 10 minutes at 325°F using the steam/bake function. The convection/bake works neither better nor worse in this oven than it does in any countertop oven. The secret is the steam/bake function. Yes it is counterintuitive to think that steam/bake would crisp anything up but take my word for it. Fries or fried chicken same thing ——steam/bake.
Edited to add that I used the tray that came with the oven and lined it with foil and put it into the toast position.
