I am sorry for the lost highlight changes.
Would you please check if the problem happens with a particular PDF document or all of your PDF documents? Is the PDF document stored on your iPad, Adobe Document Cloud, or other cloud storage (e.g. iCloud, Dropbox)?
Acrobat Reader automatically saves changes, when you close an open PDF document.
Would you add a couple of more highlight annotations to your problematic PDF document, close it by going back to the file browser, and immediately reopen it to see if the highlight changes have been saved?
Hello,I checked it and found that few documents stored as pdf save the changes while some don't when I close the document. All documents are saved on the device. There is a possibility that large/ heavy documents do not store highlight changes.I tried making many highlight changes in that document, but it is not stored/ saved.Thank you,Amit
What is the app version of Acrobat Reader for iPad and iPhone?
Would you be willing to share your PDF document with us (Adobe) so that we can investigate the problem?
I've sent you a forum private message with the instructions on how to share a file with us.
Thank you for your help.
Thank you for sharing your PDF document with us.
I downloaded your PDF document from Dropbox and opened it in Acrobat Pro DC (desktop app) first.
Unfortunately, your PDF document is damaged/corrupted beyond repair.
I do not know exactly what happened to your PDF document.
My guess is that
(a) some parts of the PDF document was lost when it was copied to your iPad or
(b) pre-existing PDF syntax errors in the PDF document caused Acrobat Reader for iPhone and iPad to fail to properly save highlight changes.
I tried to save the PDF document in Acrobat Pro DC (desktop app) to repair the damage. But as you can see in the screenshots above, Acrobat Pro was not able to fix the damage. (I believe that your PDF document had already been damaged before you uploaded it to Dropbox for sharing.)
You may be able to continue viewing the PDF document. However, neither Acrobat Pro DC nor Acrobat Reader for iPhone and iPad can save highlight changes to the PDF document any more.
I'd recommend obtaining a new copy of the same PDF document ("Robbins....pdf") and starting over. In the mobile or desktop version of Acrobat Reader, add a couple of highlight annotations, close and reopen it to see if the highlight annotations are saved.
I am sorry for your troubles. But there is not much we can do to the damaged PDF document.
Pease let us know if you have additional questions.
We found the same PDF document (with the same filename and file size) online and concluded that the original PDF document already has the invalid page number problem as shown in the first screenshot in my reply #4 in this forum thread.
The good new is that I was able to repair the problem!
I shared the repaired PDF document with you via Adobe Document Cloud. Please check the private forum message that I sent you.
You can add a couple of highlight annotations, close the document to save changes, and reopen it to see if the highlight changes are saved to the document correctly.
Please let us know what you find.
