How to Fix PDF Comments Unavailable in Acrobat Reader for Windows Phone
Question details
The user cannot view or add comments to a PDF file using Acrobat Reader on a Windows Phone, despite the commenting tools working perfectly when the same file is opened on a Windows PC.
- Product
- Acrobat Reader
- Device & OS
- Windows Phone, Windows PC
- Scenario
- Transferring a PDF via Document Cloud and attempting to review or annotate it on a mobile device.
- Observed behavior
- Comment tools are disabled, greyed out, or completely unavailable in the mobile application interface, restricting any form of annotation.
Ensure your PDF document is not restricted by security policies, as mobile PDF readers enforce digital rights management and permissions more strictly than desktop versions.
Review and Modify PDF Security Permissions on Desktop
Since mobile apps have stricter permission enforcement, checking and adjusting the PDF's security properties on your PC can restore access to comment tools.
Even if a document allows commenting on a desktop application, mobile platforms may misinterpret certain encryption levels or security flags, locking down the file. Removing security restrictions usually resolves this.
Open the affected PDF file in your desktop PDF editor. Click on 'File' in the top menu and select 'Properties'.
Navigate to the 'Security' tab. Look at the 'Document Restrictions Summary' and check if the 'Commenting' permission is set to 'Allowed' or 'Not Allowed'.
If restrictions are applied, click the 'Security Method' drop-down menu and select 'No Security'. You will need to enter the permissions password if prompted.
Click 'OK' to apply the changes, save the PDF as a new file, and upload it back to Document Cloud to access it on your Windows Phone.
Flatten PDF Comments on PC
If you only need to view existing comments on your mobile device, flattening the PDF will embed the comments directly into the document pages.
View and Add PDF Comments on Any Device with WPS Office

- 1. Open PDF in WPS Office: Launch WPS Office on your PC or mobile device and open your PDF document.
- 2. Access the Comment Tab: Navigate to the 'Comment' tab located on the top ribbon to view all available annotation tools.
- 3. Add Annotations: Use features like Highlight, Text Box, or Sticky Notes to seamlessly annotate your document.
- 4. Sync via WPS Cloud: Save your file directly to WPS Cloud, allowing you to seamlessly pick up where you left off on any synced mobile device.
Frequently Asked Questions
Why are PDF comments available on PC but hidden on mobile?
Mobile PDF applications often enforce document security policies differently or lack full support for advanced annotation layers. If the app detects certain security flags, it may defensively disable comment tools even if they are accessible on a desktop reader.
Are my existing comments lost if they don't appear on my phone?
No, the comments are still safely embedded in the file data. The mobile app is simply restricting the interface to view or edit them. Opening the document on a fully featured desktop reader will display them normally.
Can I bypass mobile security restrictions without the password?
No. Standard PDF readers respect document security. You must have the original permissions password to remove restrictions on a PC before the file can be freely annotated on a mobile device.
