Open Adobe Acrobat, click on 'Help' in the top menu bar, and select 'About Adobe Acrobat' to see if you are running the affected version (21.005.20048).

2
Check for available updates

Navigate back to the 'Help' menu and click on 'Check for Updates...'. The application will connect to the server to look for the latest patches.

3
Install the update

If update 21.005.20054 (or later) is found, follow the on-screen prompts to download and install it. Alternatively, you can download the patch directly from the Adobe Release Notes DC webpage.

4
Restart and test

Close Adobe Acrobat completely and reopen it. Click your SharePoint link again to verify that the PDF files are now displaying in the correct numerical order.
