Fix Adobe Reader Mobile Not Uploading or Crashing on iPad
Question details
The user is experiencing file upload failures, sudden app crashes, and page-position saving problems while using a PDF reader on an iPad following a recent app update.

- Product
- Adobe Reader Mobile
- Device & OS
- iPad (iOS)
- Scenario
- Uploading files, viewing documents, and navigating pages within the PDF app after installing an update.
- Observed behavior
- The application fails to complete file uploads, stops responding unexpectedly, crashes during use, and loses the last viewed page position.
Verify that your iPad has a stable internet connection for uploading files and ensure you have sufficient available storage space, as critically low storage can cause apps to freeze or crash unexpectedly.
Check Support Forums and Reinstall the Application
Reinstalling the app can clear corrupted update cache files, while checking official forums helps identify if the bug is a known issue requiring a developer patch.
Major application updates can occasionally introduce compatibility glitches with specific iOS versions or corrupt existing temporary data. Completely removing and freshly reinstalling the application often resolves these upload and performance failures.
Visit the Adobe Reader for iOS community forum to check if other users are reporting similar post-update crashes and if an immediate patch is available.
Press and hold the Adobe Reader app icon on your iPad home screen, tap 'Remove App', and then select 'Delete App' to completely remove its data.
Open the App Store on your iPad, search for the application, and download the latest available version.
Relaunch the app, sign back into your account, and attempt to upload or scroll through a PDF file to verify the stability.

Frequently Asked Questions
Why does my PDF app crash immediately after an iOS update?
App updates can sometimes introduce bugs, conflict with your current iOS version, or leave behind corrupted cache files. These issues often lead to sudden crashes when the app tries to execute memory-intensive tasks like uploading.
How can I ensure my PDF page position is saved if the app keeps freezing?
If your primary PDF reader is unstable, try using an alternative like WPS Office, which automatically bookmarks your reading progress and syncs it securely across your devices via the cloud.
Where can I find the exact version number of my iOS app?
Go to your iPad Settings, scroll down the left sidebar to find the specific app (such as Adobe Reader), and tap on it to view the version number. You can also view update history in the App Store profile page.
