I am collaborating with a friend on an excel document. He uses excel, and I use Libre Calc. Recently, he created some nifty smart-art, which of course didn’t show on my version in Libre. I made some comments and then resaved, which destroyed the smart art on the master file, so when he opened it up on his computer, all the work he had done is gone. Is there some way to undo this? Just in case it’s important, we are sharing the file in dropbox.
I am using Version: 188.8.131.52 (x64) on a PC.
Thank you for your help! (I hope someone can help!).
