Revision tools don't work

Hi. I have the revision mode on. Comments work, but when I add, delete (etc) something I don’t see different font colors, crossed-out words (etc), it just deletes or adds words as if I’m writing normally.
What can I do?
Thank you.

Hello,

if you are talking about View -> Track Changes - this is only to toggle whether you see 'em or not if Track Changes is running. Make it running using Edit -> Track Changes -> Run ( or CTRL+SHIFT+C)

Hope that helps.
