- Product
- Adobe Acrobat Reader
- Device & OS
- iPad
- Scenario
- Reading, studying, or reviewing a PDF document on an iPad and applying multiple highlights across different lines or paragraphs.
- Observed behavior
- The highlighter tool deselects automatically after a single use, forcing the user to repeatedly re-click the tool to highlight the next piece of text.
Ensure your iPad is connected to the internet and that you have your Apple ID credentials ready, as resolving this issue requires updating the application from the App Store.
Update Adobe Acrobat Reader to the Latest Version
Updating the app resolves this issue because versions 17.03.28 and later include a continuous markup feature that keeps the highlighter active by default.
In older versions of Adobe Acrobat Reader for iOS, the app's default behavior was to drop the markup tool after a single use. Based on user feedback, Adobe modified this feature in update 17.03.28 to allow continuous highlighting.
Navigate to your iPad's home screen and tap the App Store icon.
Tap on your Apple ID profile picture located in the top-right corner of the screen to open the account menu.
Scroll down to the 'Available Updates' section. Find Adobe Acrobat Reader in the list and tap the 'Update' button next to it. If it is not listed, your app may already be up to date.
Once updated, open a PDF document in Acrobat Reader. Select the Highlight tool and begin swiping over text. The tool will now stay active, allowing you to highlight multiple sections repeatedly without re-clicking.
