I understand how to resize an instance of a symbol that's a layer on an artboard (and how to specify how that resizing should work on the "master" symbol). My question is not that, it's about resizing in the other direction.
When editing a symbol in the Symbols area, if I resize it then the changed size isn't reflected on the artboards.
It appears that, basically, the layers are now considered to be resized versions of the original symbol (even though its size was never changed/overridden when originally inserted on the artboards).
Is there any way for me to get the layers to update on the various artboards after changing the original symbol size?
