Hi Stephen, thank you for being so involved on this board, it's helpful as I have searched high and low on the InVision help center and get no where.

Can you elaborate on "Better support for symbol overrides when syncing library?" I am not having much luck with symbol overrides (for nested symbols), period. I even added all of the nested symbols into the library itself in hopes that it would find them there, but still no luck. This pretty much breaks the organization my team has for our symbol library. Will there be any update on this?

I have also experienced this slow down, often to the point that Sketch crashes altogether.
