Users need to resolve an issue where PDF comments are invisible upon opening in Adobe Document Cloud via SharePoint and only appear after zooming in or out.

Fix PDF Comments Not Showing Until Zoom in Adobe Cloud Viewer
Product
Adobe Document Cloud / SharePoint
Device & OS
not provided
Scenario
Opening and reviewing PDFs with comments through SharePoint using the Adobe Document Cloud web integration.
Observed behavior
Comments are initially invisible upon opening the PDF but appear in their correct locations after the user zooms in or out on the document.
Before you start

Ensure your web browser is updated to the latest version and verify whether the issue persists across different web browsers (like Chrome or Edge) to rule out browser-specific caching issues.

Solution 1

Force Refresh the PDF Comment Layer

Use the zoom function as a quick workaround to force the Adobe Cloud Viewer to re-render missing comment layers.

Because this is a known rendering delay in the web-based viewer, forcing the page to redraw can temporarily solve the visibility issue without requiring a download.

1
Open the PDF

Navigate to SharePoint and open the affected PDF file using the Adobe Document Cloud viewer.

2
Trigger a zoom action

Click the 'Zoom In' (+) or 'Zoom Out' (-) button in the top toolbar of the viewer, or hold Ctrl/Cmd and scroll with your mouse wheel.

3
Verify comments

Check the document to ensure the missing comments have rendered in their correct locations.

Frequently Asked Questions

Why do PDF comments disappear in cloud viewers?

Cloud viewers rely on browser rendering engines. Large or complex PDF comment layers may fail to load initially due to browser caching limits, network latency, or specific rendering bugs in the web viewer's code.

Does this rendering issue happen in the standard SharePoint PDF viewer?

Usually, no. This specific delay is often tied to the Adobe Document Cloud integration within SharePoint. The native SharePoint viewer or desktop apps typically display PDF comments immediately.

How can I permanently fix this PDF comment delay?

A permanent fix requires a software update from the developer of the cloud viewer (in this case, Adobe). In the meantime, you can use workarounds such as zooming to force a page redraw, or switching to a dependable desktop PDF viewer.
