Frequently Asked Questions

Why did my PDF files disappear after upgrading to iOS 12 Beta?

Beta operating systems are preliminary versions meant for testing and often contain changes that conflict with existing app code. In this case, iOS 12 Beta introduced changes that broke Adobe Acrobat Reader's ability to render file paths correctly, making the documents appear as though they had disappeared.

Will reinstalling Adobe Acrobat Reader fix this iOS 12 Beta bug?

No, simply uninstalling and reinstalling the same version of the app will not resolve the problem because the issue lies in the compatibility between that specific app version and the beta OS. You must install the patch (version 18.07.30 or newer) from the App Store.

How can I open local PDF files if Acrobat Reader continues to crash on iOS?

You can use Apple's built-in 'Files' app to preview PDF documents natively, or you can download a reliable third-party alternative like WPS Office from the App Store to open, read, and manage your local PDF files without issue.
