Hi yaph79276059​,

Sorry for the problem.

I am not sure if the PDF documents are actually corrupted.

Would you try restarting your iPad/iPhone after updating to the latest version (17.12.15) of Acrobat Reader?

Restart your iPhone, iPad, or iPod touch - Apple Support

Restarting your device should clear the bad state.

When you see the alert again, please choose to create a local copy so you will not lose new changes.  The copy will appear in the "Local" file browser in Acrobat.

Please let us know what you find.

Thank you.

Hi again,

At this point, I'd recommend the following steps.

1. Make backup copies of the existing Local files (i.e. transfer the files to your Windows/Mac computer).

2. Open the backup copies in the desktop version of Acrobat Reader on your Windows/Mac computer.
   Can you open the files in the desktop version of Acrobat Reader?
   Proceed to the next step only when you confirm that the files are not corrupted.
3. Uninstall Acrobat Reader on your iPhone/iPad. (Note that iOS will erase all of your local files and preferences.)
4. Restart your iPhone/iPad.
   Restart your iPhone, iPad, or iPod touch - Apple Support
5. Reinstall Acrobat Reader on your iPhone/iPad.
6. Transfer the backup copies from your Windows/Mac computer to your iPhone/iPad.

Sorry for your trouble.

Hi yaph79276059​,

Acrobat Reader displays the alert with the title "Document Could Not Be Saved" when it fails to save changes to the PDF document due to an error.

Because the PDF document is already corrupted/damaged, you will not be able to save any additional changes to it (no matter how many times you try).

We can inspect the corrupted PDF document and try to repair damage, if you are willing to share the PDF document with us (Adobe).

I sent you a forum private message yesterday.  Please respond if you would like us to try repairing the corrupted PDF document.

Thank you.

HI yaph79276059​, rsn18022893​,

We just released Acrobat Reader 18.01.15 to the App Store today (January 10, 2018).

As always, we'd highly recommend making backup copies of your valuable PDF documents regularly.

Please try it out by making small changes to a large PDF document and see if it works for you.

We apologize for the inconvenience caused by the previous version.
