Frequently Asked Questions

Why can I see PDF comments in Acrobat Pro but not in Adobe Reader?

This discrepancy usually happens due to a corrupted Adobe Reader installation, an outdated software version, or specific network permissions that restrict the free Reader application from reaching the review server.

How do I know if the shared PDF review server is down?

If the server is down, no users will be able to connect or sync comments, even on Acrobat Pro. You can confirm this by asking the document creator to check the server status or network drive availability.

Can I view shared review comments offline in Adobe Reader?

No, shared review comments require an active connection to the review server to download and synchronize the latest annotations made by other collaborators.

What should I do if updating Adobe Reader doesn't fix the server connection?

If updating and repairing Adobe Reader fails, try completely uninstalling the software, restarting your computer, and reinstalling the latest version directly from the official Adobe website.
