I haven't noticed any change for anything that I do on my iPad since installing 16. I don't do much on it though.
Age?...per joemike's advice about needing the latest hardware for some stuff. Anyway, we're like you....haven't been doing a lot that matters, although I will admit to an interest in the Apple pen functions.
