Scenario

Solution 1Recommended

Verify Your Account and Check the Web Portal

Missing documents are frequently caused by logging into a different account. Checking the web version confirms whether the files are safe in the cloud.

Mobile apps often support multiple sign-in methods (such as direct email, Google, or Apple). Using a different method can create a completely separate, empty account workspace.

1
Log out of the mobile app

Tap on your profile icon in the Adobe Reader Mobile app settings and select 'Sign Out' to clear the current session.

2
Access the online portal

Open a web browser on your computer or mobile device and navigate to Acrobat Online (https://acrobat.adobe.com/).

3
Sign in with original credentials

Click the 'Sign In' button and use the exact Adobe ID or social sign-in method you originally used when uploading the PDFs.

4
Check the Documents section

Click on the 'Documents' tab in the top navigation bar to verify if your missing files are listed and available on the server.

Verify Your Account and Check the Web Portal
Account verification: If the files appear on the web portal, you simply need to sign into the mobile app using those exact same credentials.

Frequently Asked Questions

Why are my PDF files suddenly missing from my mobile viewer?

This usually happens if the app signs you out automatically, you accidentally log in with a different account, or if there is a temporary syncing delay between the mobile app and the cloud server.

How do I recover a deleted PDF file on my mobile device?

If you accidentally deleted a file, check the 'Recently Deleted' or 'Trash' folder within the app or your connected cloud storage service. Most platforms retain deleted files for up to 30 days before permanent deletion.

Does uninstalling the mobile PDF app delete my documents?

If your documents are saved to the cloud, uninstalling the app will not delete them. You can access them again by reinstalling the app and logging in. However, locally saved files not backed up to the cloud may be permanently removed depending on your operating system.
