Users can annotate and share files with colleagues and customers from within the Hub. This allows for collaboration and feedback/reviews. *NOTE: Annontations are shared via email, not via HubShare.
You can choose to share files:
When sharing files with annotations, users can view these annotations in the Hub. PDF files with annotations can be edited in native PDF software tools such as Adobe Reader.
With Annotations Flattened
When sharing files with annotations flattened, users can just view the annotations. This feature is specifically for compatibility for emails exchanged over iOS. Flattening annotations simply means painting the annotations directly on the page to which they belong, so that they are not editable. If the annotations have Notes, they may not appear correctly in flatten annotations.
