I bought this several months ago and have used it in many capacities- baking, reheating and toasting. However, if the crumb tray is left in the oven while toasting, the underside of the bread remains soft and does not toast. It toasts fine if I remove that tray, which seems to defeat the purpose of the tray, because then crumbs can fall to the bottom of the oven. Now I'm wondering if I should remove it when baking, as it seems to take several minutes longer for some things to bake even if I use a higher temperature. It seems like the tray blocks the heat underneath the food. I would like to know if it is meant to be left out 
sometimes to allow for the convection air flow to be more effective. Other than this issue, I do like it.
