- Product
- Adobe Acrobat Pro DC
- Device & OS
- not provided
- Scenario
- Collaborating on documents and attempting to filter feedback in shared review PDFs after an automatic software update.
- Observed behavior
- Adobe Acrobat completely freezes and becomes unresponsive when the Filter Comments button is clicked, rendering shared-review files unusable.
Ensure you have saved any open work in other applications, as resolving application freezes may require you to force-quit Adobe Acrobat and could result in unsaved data loss.
Update Acrobat to the Latest Release
Installing the most recent patch usually resolves version-specific bugs introduced in previous automatic updates.
This freezing behavior is a known version-specific defect in certain builds (like 2019.008.20080). Adobe frequently releases patches to address these critical rendering bugs.
Launch Adobe Acrobat and click on 'Help' in the top application menu bar.
Select 'Check for Updates' from the dropdown menu and allow the system to scan Adobe's servers for the latest software patches.
Follow the on-screen prompts to download and install the update. Once finished, restart Acrobat and test your shared review PDFs to see if the Filter Comments button works normally.

Roll Back Acrobat to a Previous Stable Version
If the latest update does not fix the issue, rolling back to an earlier stable build can temporarily restore functionality for shared reviews.

Frequently Asked Questions
Why does Acrobat only freeze when clicking the Filter Comments button?
This is typically caused by a specific software bug in certain Acrobat update builds where the rendering engine fails to properly parse the metadata of shared review comments, resulting in an immediate application lock-up.
Will my shared review comments be lost if Acrobat freezes?
Any unsaved changes or new comments made right before the freeze may be lost if they weren't synced to the server. However, previously synced comments stored in the shared review file will remain intact once you reopen the document.
Can I manage my PDF shared review comments using other software?
Yes, standard PDF comments are universally compatible. You can open the same PDF file in alternative PDF software like WPS Office to view, filter, and reply to comments without experiencing the Acrobat-specific crashes.
