I mean, that is purely subjective in my opinion. I think especially in this update the daughters make clear that they are their canon age. Someone like Olivia might look younger, I agree, but I don't see or write her with that in mind. Sophie, Lina, Yukiko, Morgan and Sarah both look old enough in my opinion and given the way how they talk about themself etc should also make that clear. But like I said, I get that looks are subjective and I can respect that. It doesn't change the fact that the canon ages are the real ages, though.
