Question details
Users are experiencing issues with Adobe Acrobat shared reviews, including browser loading failures, missing invitation emails, untracked recipients, and misaligned comments.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Initiating or participating in a shared PDF review process to collect feedback.
- Observed behavior
- Shared PDFs fail to load in browsers, invitation emails are not received by recipients, responses disappear from tracking, and comments cluster in a single location rather than their intended spots.
Before troubleshooting, verify that all review participants are using a recently updated version of Adobe Acrobat or Acrobat Reader and have a stable internet connection.
Download and Open the PDF in the Desktop Application
Opening shared PDFs in web browsers can cause loading failures and misplaced comments. Downloading the file locally forces the use of official commenting tools and resolves formatting issues.
Web browsers often use default, lightweight PDF previewers that do not support advanced Adobe commenting features. This causes annotations to synchronize incorrectly or bunch together in one spot.
Instruct recipients to download the shared PDF attachment to their local computer storage instead of clicking to open it directly within their web browser.
Right-click the downloaded PDF file, select 'Open with', and choose Adobe Acrobat or Adobe Acrobat Reader.
Navigate to the 'Comment' tool panel on the right side of the workspace and use the official annotation tools to ensure comment positions are accurately preserved.

Troubleshoot Missing Invitation Emails and Delivery Rules
If recipients are not receiving review invitations, the mass emails may be blocked by spam filters, organizational firewalls, or email client limits.
Use the Official Distribute Form Workflow
To prevent disappearing recipients and ensure responses are tracked properly, always use the dedicated Distribute tool rather than sending manual email attachments.
Collaborate on PDFs Effortlessly with WPS Office
Avoid browser compatibility errors and email attachment limits by using WPS Office. With powerful PDF reading and commenting tools, combined with built-in cloud sharing, team collaboration becomes fast, trackable, and reliable.
- 1. Open your PDF: Launch WPS Office and open your PDF document from your local drive.
- 2. Add comments: Navigate to the 'Comment' tab at the top menu to add highlights, sticky notes, and text annotations accurately.
- 3. Generate a sharing link: Click the 'Share' button in the top right corner to upload the file securely to the WPS Cloud.
- 4. Share with colleagues: Copy the generated link and send it to your team. They can view the document and collaborate without dealing with bulky attachments.

Frequently Asked Questions
Why are all the PDF comments appearing stacked in one location?
This typically happens when participants view and annotate the PDF in a web browser or a basic third-party previewer instead of a dedicated PDF application. Web browsers often strip coordinate data from annotations. Asking them to download the file and use standard commenting tools in a desktop app will fix this.
Can I resend a shared review invitation if a recipient didn't get it?
Yes. If the original email was caught by a spam filter, you can open the Tracker tool in Adobe Acrobat, select your specific shared review from the list, and choose the option to 'Add Reviewers' or 'Email Reviewers' to send a fresh notification.
Is it better to send a PDF attachment or a cloud link for shared reviews?
Sending a cloud link is generally recommended. It prevents issues with email servers blocking large file attachments, minimizes spam filter triggers, and ensures everyone is accessing and commenting on the exact same version of the document.
