Frequently Asked Questions
Why did the alphabetical index disappear from my Acrobat Reader app?
The missing alphabetical index was caused by a software bug introduced in a previous update of Adobe Acrobat Reader for iOS. It has since been resolved by the engineering team starting from version 18.10.01.
Can I manually sort my PDF files by name in the native iOS Files app?
Yes. If you use the native Apple Files app to browse your PDFs, you can swipe down slightly in any folder to reveal the sorting menu, tap the 'Sort' option, and select 'By Name' to arrange your files alphabetically.
Will updating Acrobat Reader delete my existing PDF files?
No, updating an app through the Apple App Store only replaces the application's software files. Your personal PDF documents, custom settings, and downloaded files will remain safely intact on your iPad or iPhone.
What should I do if the alphabetical index is still missing after updating?
If the index doesn't appear after updating to the latest version, try force-closing the app by swiping up from the bottom of your screen and swiping the app away. Then restart your device. If the issue persists, you may need to back up your files, then uninstall and reinstall the app.
