How to Fix PDF Attachment and Viewing Issues in the Manulife App

Product: Manulife App / PDF Reader
Device & OS: not provided
Scenario: Submitting health claims via the Manulife app using PDF attachments.
Observed behavior: PDF files appear to attach but cannot be downloaded or viewed afterward, despite the process working previously.

Before you start

Verify that your PDF files are not corrupted or encrypted by opening them directly in a standalone PDF reader before attempting to upload them to the health app.

Solution 1Recommended

Verify PDF Integrity in a Standard PDF Reader

Check if the PDF file itself is valid and can be opened outside the third-party app.

Sometimes files get corrupted during download or saving. Testing the file in a dedicated PDF application helps isolate whether the issue lies with the file or the Manulife app.

Locate the file

Open your mobile device's file manager and locate the PDF file you intend to upload.

Open with a PDF app

Tap on the file and choose to open it using a dedicated PDF reader app, such as WPS Office or Adobe Acrobat Reader.

Check file contents

Scroll through the document. If it opens successfully and displays properly, the issue is likely isolated to the Manulife app's attachment handler.

Verify PDF Integrity in a Standard PDF Reader

Note: If the file fails to open in the standalone reader, you will need to re-download or recreate the PDF document before uploading.

Solution 2

Clear App Cache or Reinstall the Manulife App

Clear out temporary data that might be causing glitches with file attachment and viewing capabilities.

Solution 3

Optimize and Compress the PDF File

Frequently Asked Questions

Why do PDF attachments fail to upload or view in mobile apps?

Uploads and in-app viewing can fail due to the PDF file size exceeding the app's internal limit, file corruption, or outdated cache data within the specific application handling the upload.

How do I know if my PDF file is corrupted?

If you cannot open the PDF file in a standard viewer like WPS Office or Adobe Acrobat Reader, or if it displays blank pages and error prompts upon opening, the file is likely corrupted.

Can I upload a password-protected PDF for health claims?

Most third-party platforms, including health claim apps, cannot process encrypted or password-protected PDFs. You need to remove the password security using a PDF editor before uploading the file.

What is the ideal file size for PDF uploads on mobile apps?

While the exact limit varies by app, keeping your PDF file size under 5MB usually ensures a smooth and successful upload process.
