Frequently Asked Questions

Why does Acrobat for iOS say "issue preparing the shared copy"?

This error typically occurs due to temporary app cache glitches, an unstable internet connection while attempting to sync cloud files, or an outdated version of the Acrobat Reader iOS application.

Can a corrupted PDF cause sharing errors on iPhone?
