Just cleaning up some folders and found that I actually did get screenshots!
Same basic screen, but one shows the expanded 'Accept' and 'Reject' text. Very promising!Bill Blais supported this idea ·Bill Blais commented
So, I can confirm that they're working on it, because I had it. Briefly.
I am a 'First Release' user in my tenant and 2 weeks ago I stumbled across Track Changes functionality in the Review ribbon in Word Online while editing a doc with a coworker! And it worked as expected (color changes, strikethroughs, named edits, etc.)! I was thrilled! It wasn't available for any non-First Release users, but that was fine.
Now, however, it's gone. I wish I'd taken a screenshot to prove my sanity, but I checked and our sysadmin hasn't changed any O365 settings. Anyone else experience this?
