There are multiple issues when attempting to read a PDF file with VoiceOver. These issues are sporadic in nature; problems identified include:
- Upon opening a PDF document, the document sometimes is not seen by VoiceOver at all;
- PDF documents sometimes are not read in their entirety by VoiceOver;
- An inability to swipe around the screen to locate the beginning of a document, necessitating that VoiceOver users explore by touch or use the "Headings" Rotor option to attempt to locate the text; and
- An inability to consistently navigate PDF documents by heading, even when headings are present.
