PerfectIt Cloud works with 'track changes'. However, there can be a small loss of accuracy in documents with lots of tracked deletions.
To minimize any possible loss of accuracy, markup/tracked changes should not be showing while PerfectIt is running. If you have tracked revisions in your document, you should click the 'Review' tab in Word's ribbon. Then choose "Simple Markup" or "No Markup".
We want to improve the accuracy with tracked changes, but we are dependent on improvements from Microsoft. Here's how you can help us make that happen.
