Use VoiceOver to preview comments and track changes in Pages on iPhone
You can use VoiceOver to read annotations made by other people collaborating on a document. Annotations are separated by VoiceOver into three groups: comments, highlights, and tracked changes. VoiceOver reads comments and identifies the person who made the comment, describes highlights (including the color of the highlight), and when you select a tracked change, VoiceOver speaks whether a potential change is an addition or deletion, and lets you preview the change before you accept it.
