Update the Adobe Acrobat App
Installing the latest version of Acrobat resolves known software bugs that prevent annotations from saving.
Adobe has identified and fixed a bug in older versions of the Acrobat iOS app that caused markups to disappear. Updating to the latest version is the most effective way to resolve this error permanently.
Open the Settings app on your iPhone or iPad, scroll down to find Adobe Acrobat, and tap it to view your currently installed version number.
Open the App Store on your device and search for 'Adobe Acrobat' in the search bar.
If you see an 'Update' button next to the app name, tap it to download and install the newest version. If it says 'Open', you are already on the latest version.
Relaunch Adobe Acrobat, open your PDF file, add a test annotation, and tap 'Done' or 'Save' to confirm the issue is resolved.

Restart Device and Check Storage Space
Clearing temporary glitches and ensuring your device has enough storage can help the app write and save files correctly.

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This is typically caused by a known bug in outdated versions of the Adobe Acrobat mobile app.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.
