I have all the settings correct, but the Track Changes aren't showing. It hasn't been working correctly since this version was installed, Adobe CC 2017.0 release, 220.127.116.11. Anyone else experience this? - Theresa
Are you viewing the story or galley mode?
Could this be due to a third party plugin like Blacklining not being updated/installed for CC2017?
I'll bet you accidentally pressed the keyboard shortcut, Command/Ctrl-7 in IC, that toggles the View preference to Hide/Show Changes -- that is, to hide/show tracked changes markup. Or in InCopy, you pressed the eyeball icon in the Track Changes toolbar, which also toggles the visibility on/off.
So check your View menu in InCopy (Hide/Show Changes is the last item), or your View > Story Editor submenu in InDesign, and if it says Show Changes, select that to show them.
And a random thought...
Whats are your track changes color preferences?
