I have the oven for almost two months and enjoy learning and using its numerous features.
The control touch screen is intuitive to operate.  The Wi-Fi connection was easy to install and the app performs very well on my iPhone and iWatch - amazing!  Love the camera on the top oven.  BUT there was one glaring omission that I cannot understand was neglected - there is no Operation Manual.  I still have yet to learn how "Steam Cleaning" functions and some other setting.  It would be nice to know when to use the Convection setting instead of Air Fryer for specific foods.  This is all left to trial and error and frustration.
