Solution 1Recommended

Verify Connectivity and Update Acrobat Pro

Network instability or an outdated application version often disrupts the communication between the Acrobat desktop client and Document Cloud.

Shared reviews rely on real-time server synchronization. A momentary drop in your network or a known bug in older versions of Acrobat CC can trigger this error.

1
Check network stability

Open a web browser and navigate to any reliable website to confirm your internet connection is active and stable.

2
Check for software updates

Open Adobe Acrobat Pro. Click on the 'Help' menu in the top toolbar and select 'Check for Updates'.

3
Install available patches

If an update is available, follow the on-screen prompts to download and install it, then restart your computer.

4
Retry the sync action

Relaunch Acrobat, open the shared PDF review, and try resolving or replying to the comment again.

Frequently Asked Questions

Why does Acrobat say 'We weren't able to sync your action'?

This error typically occurs due to an unstable internet connection, a temporary Adobe Document Cloud server outage, or bugs present in outdated versions of Acrobat DC.

Will I lose my comments if the Acrobat sync fails?

Your comments are generally cached locally on your device. However, until the synchronization is successful, other collaborators will not see your changes. It is recommended to save a local copy of your file to prevent accidental data loss.

Can I add comments to a shared PDF while offline?

Yes, you can continue working and adding comments to a downloaded shared PDF offline. Acrobat will attempt to sync your new comments to Document Cloud automatically once you reconnect to the internet.

How do I check if Adobe Document Cloud is currently down?

You can visit the official Adobe System Status website on your browser. This dashboard provides real-time updates and historical data regarding any outages affecting Document Cloud services.
