Update the Mobile App and iOS Version

Outdated application versions or iOS incompatibility often cause selection and editing glitches. Updating ensures bug fixes are applied.

Software updates frequently contain patches for known UI glitches and compatibility fixes for newer iOS versions. Running an outdated app on a newer iOS system can cause the text selection tool to fail and highlight the whole page instead.

Frequently Asked Questions

Why is the entire PDF page being selected when I try to edit text?

This usually happens if the PDF is a scanned image (a flattened document) rather than a text-based PDF, or if there is a bug in the app's selection tool. Using a PDF editor with an OCR (Optical Character Recognition) feature or updating the app can resolve this.

Does reinstalling my PDF app delete my premium subscription?

No, your premium subscription is tied to your account credentials or your Apple ID, not the local app installation. Simply log back into your account or tap 'Restore Purchases' after reinstalling to regain your premium editing features.

Can I edit scanned PDFs on my iPhone?

Standard PDF editing tools only work on native text-based PDFs. To edit a scanned PDF on a mobile device, you need to use an app that supports OCR to extract and convert the image into editable text.

What details should I include when contacting app support for editing issues?

Always include your specific device model, exact iOS version, the app version number, and a screen recording showing the issue (such as the full-page selection error) to help the support team diagnose the problem faster.
