Question details
Users are unable to save new PDF documents or push edits of existing PDFs to their connected cloud storage services via the mobile reader app.

- Product
- Adobe Acrobat Reader Mobile
- Device & OS
- not provided
- Scenario
- Editing or creating a PDF file on a mobile device and attempting to save the changes directly to a connected cloud storage provider.
- Observed behavior
- The application fails to sync or save the document to the cloud, either displaying an error message or failing to reflect the applied edits.
Ensure your mobile device has a stable internet connection and that you are logged into your cloud storage account with the appropriate permissions to modify files.
Identify and Resolve Cloud Storage Sync Issues
Determine if the issue lies with a specific cloud provider, an expired authentication session, or a temporary app glitch.
Cloud save errors on mobile devices often stem from expired login tokens for third-party cloud integrations (like Google Drive, Dropbox, or OneDrive) or connectivity drops during the saving process. Re-establishing the connection usually clears the error.
Ensure you have an active Wi-Fi or cellular data connection, and toggle Airplane Mode on and off to reset your network.
Navigate to the 'Files' or 'Locations' tab in your app, locate your cloud storage provider, tap the settings icon, and select 'Sign Out' or 'Remove'. Sign back in to refresh the connection.
Take note of any specific error codes displayed when tapping 'Save'. If editing an existing file, ensure the file is not locked, shared as read-only, or open on another device.
Open the Google Play Store or Apple App Store, search for your PDF reader app, and tap 'Update' to install the latest bug fixes.

Workaround: Save Locally Before Uploading
Bypass app-specific cloud sync errors by saving the document to your device's local storage and manually uploading it.
Edit and Save PDFs to Cloud Seamlessly with WPS Office
If your current PDF reader continues to fail when saving to the cloud, switch to WPS Office. WPS provides a powerful built-in PDF reader and editor with its own highly reliable WPS Cloud, plus flawless integration with third-party drives.
- 1. Download WPS Office: Install WPS Office from your device's app store and open the application.
- 2. Open and edit your PDF: Tap 'Open', select your PDF file, and use the robust tools to make necessary edits or annotations.
- 3. Save to WPS Cloud: Tap the 'Save' icon; changes are automatically and securely synced to WPS Cloud if auto-save is enabled.
- 4. Save to third-party clouds: Alternatively, select 'Save As' and choose connected third-party clouds like Google Drive or Dropbox to push the file directly.

Frequently Asked Questions
Why does my mobile PDF app say 'upload pending'?
This usually happens when the app loses its network connection during the save process or if the cloud service's servers are temporarily down. Reconnect to a stable Wi-Fi network and restart the app to resume the upload.
Can I recover PDF edits if the cloud save failed?
If the app closed abruptly before syncing, your edits might be lost unless they were cached locally. Always check the 'Recent' files tab in the app to see if a local temporary version was preserved.
Does saving to third-party clouds like Google Drive work differently than native document clouds?
Yes, saving to third-party clouds requires special API permissions granted by your device. If a system update revokes these permissions, you may need to sign out and sign back into your Google Drive or Dropbox account within the PDF app settings.
How can I check if the PDF is read-only on the cloud?
Navigate to the file in its native cloud storage app (e.g., OneDrive or Google Drive) and check the file properties. If it is marked as read-only, locked by another user, or if you lack edit permissions in a shared folder, you will not be able to save changes directly.
