i have it in my ipad and i have adobe reader 15.1.0
Is the problem (of Acrobat Reader closing unexpectedly) specific to a particular PDF document? Or does the problem happen with all of the five PDF documents that you have?
First, would you please ensure that you make backup copies of your PDF documents using iTunes?
It is possible that your iPad is running out of local storage space.
From the Home screen, go to
- iOS 8: Settings > General > Usage > Manage Storage
- iOS 9: Settings > General > Storage & iCloud Storage > Manage Storage
Is Acrobat Reader for iOS taking up a large portion of the local storage?
Once you confirm that your PDF documents are backed up, you could uninstall and reinstall Acrobat Reader for iOS and restore one document at a time to see if it stops closing unexpectedly.
Please let us know what you find. Thank you.
