Question details
The user needs to recover PDF annotations and comments that disappeared from a presentation after a recent software update, resulting in hours of lost work.
- Product
- Adobe Acrobat Reader
- Device & OS
- not provided
- Scenario
- Opening previously saved PDF files or saving a presentation after updating the PDF reader software.
- Observed behavior
- Annotations and comments are entirely missing or failing to display within the document after the update.
Ensure you have backup copies of your PDF files before making any software changes, and try opening the document in a web browser to check if the comments are still embedded in the file.
Check Comment Display Settings in Acrobat
Use this solution to ensure that software preferences aren't hiding your comments, which commonly occurs after an update resets default settings.
Sometimes software updates reset user preferences, causing specific toolbars or annotation layers to become hidden. The comments are often still in the document but are just toggled out of view.
Launch your PDF reader. Go to 'Edit' > 'Preferences' on Windows, or click the application name > 'Preferences' on Mac.
Select the 'Commenting' category from the left-hand menu pane.
Ensure that the settings for viewing comments are enabled and not configured to hide annotations. Click 'OK' to save your changes.
Go to the 'View' menu, select 'Show/Hide', then 'Navigation Panes', and click 'Comments' to force the comments pane to display your saved notes.
Repair the Application Installation
Software updates can sometimes corrupt background application files. Repairing the installation can restore missing features.

Frequently Asked Questions
Why do my PDF comments suddenly disappear?
Comments can disappear when software updates inadvertently reset your display preferences, if there is a file corruption during the save process, or if the PDF is opened in a viewer that doesn't fully support advanced annotations.
Are my missing PDF comments permanently deleted?
Not necessarily. In many cases, the comments are still safely embedded within the file's metadata but are hidden by the PDF viewer's current settings. Opening the file in a different, highly compatible PDF reader like WPS PDF can help verify if the data is still there.
How can I prevent losing PDF comments in the future?
Always save a backup version of your document before applying large software updates. You can also 'flatten' your PDF if you want your comments to become a permanent, uneditable part of the document page.
Does WPS Office support reading comments made in Adobe Acrobat?
Yes, WPS PDF provides excellent compatibility with standard PDF formats. It accurately displays annotations, highlights, and comments originally created in Adobe Acrobat and other major PDF editors.
