Frequently Asked Questions

Why do my PDF highlights disappear after I click Done in Acrobat?

This is typically caused by a known bug in outdated versions of the Adobe Acrobat mobile app. Updating the app through the App Store usually resolves the issue and allows your highlights to save correctly.

Can low device storage prevent apps from saving PDFs on iOS?

Yes, if your iPhone or iPad is running out of storage space, apps may fail to write new data to the disk, which can result in lost annotations, system errors, or app crashes.

How do I save a copy of my PDF with annotations in Acrobat for iOS?

To save a copy, tap the three-dot menu icon located in the top right corner of the Acrobat app while viewing your document, and select 'Save a Copy'. This is a helpful workaround if the app struggles to overwrite the original file.
