Hey there!
Loving webflow but just encountered an annoying bug. I found that the “unlink from symbol” functionality isn’t working for background images. I’m able to unlink a symbol instance from the symbol and update the text just fine, but upon editing the unlinked symbol to change the background image, it still updates the other instances of the symbol.
EDIT: As I work with unlinked symbols more, I also just found that editing the width/margin/padding, etc. of a div is also updating all symbol instances as well as unlinked symbol instances the use the same reference symbol.
Let me know if there is anything I can do here to help!
