Word Online: 'Catch up' button?

Frequent Contributor

Hi, for the past few weeks I'm seeing this button. When I open a document, the button is active for 2 or 3 seconds then it turns inactive. 





A MS support tech told me it's ~for comparing documents, but I can't see how to do that.


Can anyone please explain what it is for and how to use it?


Thanks in advance. :smiling_face_with_smiling_eyes:

That support rep didn't know what he/she was talking about.


Catch Up is for keeping track of changes and comments.  It's supposed to show you what's being going on in a document since you looked last.


It seems to work just fine for that.  I like it.  Unfortunately, it's only for Word Online so far, which is a bummer, since Word online is too basic for my organization's needs.

HI @DavisMichael, yes, it never made sense to me. Anyway, it seems to have been removed, as I haven't seen it for a while now.
