Device & OS
iPad
Scenario
Attempting to access and sign a cloud-uploaded PDF document on a mobile device.
Observed behavior
Files uploaded from the iPad are visible online, but the PDF uploaded from the computer is missing from the iPad app's document list.
Before you start

Ensure your iPad has a stable internet connection so the application can properly reach the cloud servers and synchronize your document list.

Solution 1Recommended

Verify Account Credentials and Force Synchronization

Confirm that both devices use the exact same account and force the iPad application to refresh its document list by signing out and back in.

Cloud storage applications restrict file access strictly to the email address used during the upload. If there is a slight mismatch in accounts or if the mobile app's cache is outdated, newly uploaded files from other devices will not appear.

1
Verify your email address

Check the account settings on your computer to ensure the email address you used to upload the PDF matches the one currently logged into your iPad app.

2
Sign out of the mobile app

Open the Fill & Sign app on your iPad, tap on your profile icon or the settings menu, and select the option to Sign Out.

3
Sign back in

Re-enter your credentials to sign back into the application using the verified email address.

4
Allow the list to synchronize

Leave the app open on the main document list screen for a few moments to allow it to fetch and sync the latest files from the cloud servers.

Verify Account Credentials and Force Synchronization
Synchronization Complete: Once the sync is finished, your computer-uploaded PDFs should be fully visible and ready for you to fill and sign.

Use WPS Office for Seamless Cross-Device PDF Signing

WPS Office provides robust and reliable cloud synchronization, allowing you to easily upload PDFs on your PC and instantly access, fill, and sign them on your iPad without syncing errors.

  1. 1. Install and Log In: Install WPS Office on both your computer and your iPad, then log in to both devices using the same WPS account.
  2. 2. Upload to WPS Cloud: On your computer, open the PDF in WPS Office and save it directly to the WPS Cloud.

Frequently Asked Questions

Why are files uploaded from my iPad visible online, but PC uploads are not on my iPad?

This usually happens due to a caching delay on the iPad app or mismatched account credentials. The app may need to be forced to fetch the latest server data by signing out and back in.

Can a weak Wi-Fi connection prevent PDFs from showing up?

Yes. If your iPad is on a weak or unstable network, the mobile application may fail to synchronize and download the index of newly uploaded files from the cloud server.

Is there a file size limit that prevents my PDF from syncing?

Most cloud services impose file size limits. If your PDF is exceptionally large, it might have failed to upload completely from the PC or timed out while downloading to the iPad.
