Frequently Asked Questions

Why does my mobile PDF reader keep crashing on my iPhone?

App crashes are often caused by software bugs, compatibility issues with a new iOS update, or corrupted app cache. Developers frequently release patches, so keeping your app and device updated is the best preventative measure.

Will I lose my cloud files if I reinstall a crashing app?

No, your cloud files are stored securely on remote servers, not locally on the app itself. As long as you log back in with the same account credentials after reinstalling, your cloud files will remain fully accessible.

Can I use another app to open my PDFs if my main reader isn't working?

Yes, iOS has built-in preview tools for basic reading. For advanced viewing and editing, you can use powerful third-party alternatives like WPS Office, which natively supports PDF viewing, editing, and cloud synchronization.
