Question details
The user needs a solution for text comments not rendering visually on PDF documents in SharePoint.
- Product
- Adobe Acrobat for SharePoint
- Device & OS
- not provided
- Scenario
- Reviewing and collaborating on PDF documents using the Adobe Acrobat integration within Microsoft SharePoint.
- Observed behavior
- Text comments added to PDFs become invisible on the page, although they can still be selected, printed, and viewed in Microsoft Teams or the document's comment list.
Ensure you have a stable internet connection so SharePoint can sync your recent changes. It is also helpful to verify if your current web browser is updated to the latest version.
Force the Comment Text to Re-render
Use this quick workaround to make invisible text comments reappear by forcing the application to update the document's visual state.
This rendering glitch often happens due to temporary synchronization or cache issues between SharePoint and the Acrobat web viewer. Making a minor edit forces the engine to redraw the text on the screen.
Close the affected PDF file in SharePoint. Refresh your browser (Chrome or Edge) and click on the document to open it again.
Locate the invisible comment either by selecting its blank space on the page or by clicking it in the right-hand comment list. Click to edit the text.
Type a single blank space at the end of the comment text, then press Enter or click outside the comment box. This action should force the text to render visibly on the page.

Verify with a Local Copy and Update Software
Download the file to check if the issue is limited to the SharePoint web environment, and apply necessary software updates.

Frequently Asked Questions
Why are my PDF comments visible in Teams but not in SharePoint?
Microsoft Teams and SharePoint can sometimes cache document previews differently or utilize different rendering states. A synchronization delay in the Adobe Acrobat SharePoint integration might cause comments to load correctly in the Teams viewer but fail to render in the browser-based SharePoint viewer.
Will printing the PDF show the invisible comments?
Yes, typically the invisible text comments remain safely stored in the document's metadata. Even if they fail to display on your screen due to a web rendering bug, they will usually appear normally when the document is printed or exported.
How do I report this intermittent rendering issue?
You can report this bug to Adobe and Microsoft support. Be sure to provide specific details, including your web browser version, the version of the Acrobat SharePoint integration, the exact workflow you were using, and whether the issue is reproducible across different devices.
