If you cannot see tracked changes when you open your edited document, then you may need to disable Simple Markup. Take the following steps to display the tracked changes.
Step 1:
Open your document in Microsoft Word 2013 and click on the Review tab.
Step 2:
Notice that the display is set to Simple Markup, which is the default document view in Microsoft Word 2013.
Step 3:
Click the drop-down arrow and scroll down to select All Markup. Tracked changes should now appear.
Step 4:
If changes are shown inline, then you can make the document easier to read by showing them in balloons. Select the Show Markup drop-down, then Balloons, then Show Revisions in Balloons.
Step 5:
Your document should now show all tracked changes, and comments will be shown on the right-hand side of the screen.
