Are you sure you are opening the very same file in which you made changes from the very same location where you saved it?
Which OS are you using?
Are you facing this issue with a specific file? Have you tried commenting on other files and checked if your changes are saved?
Do you get changes saved pop-up when you close the pdf after making the necessary changes?
im running iOS 8.4.1. Yes I'm sure it's the same file.
But actually sometimes it saves and other times I highlight for a long time, save it and when I open it again Im surprised that all the highlights and other work is gone.
I faced this issue with multiple files.
also sometimes I get a pop up and sometimes I don't.
Jag vet vad det är vill ha det på svenska
This is a known defect in Acrobat Reader for iOS 15.2.x. We have already fixed the defect and submitted the new version containing the fix to the App Store for review. Upon Apple's approval, the new version of the app will become available in the App Store.
We apologize for the inconvenience this may have caused.
I have been having this same exact issue and not to exaggerate but it's ruining my life here while I'm trying to study. Please fix this terrible glitch ASAP. I keep losing my highlights after reading a whole chapter and I come very close to tossing my iPad across the room. Intermittently saving doesn't help either. PLEASE FIX.
Hi alia22512767 and susana23354265,
We just released Acrobat Reader for iOS version 15.3.0 on January 5, 2016.
This release includes the fix for the defect that you have encountered.
Would you please give it a try and let us know if it works for you?
I am getting a similar thing. I am an editor working on long documents. I have mobile link on and sometimes I am working on a file that's in Document Cloud and the app will suddenly close the document and go to my local folder. But when I try to go back to the Document Cloud folder I have to sign back in again. Then, when I go back to the original file, any recent comments and highlights I've made have disappeared. It tends to be after I have left the app running but aren't actually working on it i.e. if I get called away. I have version 16.03.15, but it did the same thing on the last version.
