Someone I know made tons of comments on PDF's over months using Adobe Acrobat Reader DC; she checked that the comments were saved (i.e., they appeared after closing/re-opening the document, many times). Today, all her comments on her files are gone. Any ideas???
PS. Version latest, 20.006.20034.
I have had the same issue twice, last week & today
This just happened to me. I even did the same thing your friend did and closed the PDF and opened it right away again to see if the comments were there and they were. It seemed as though they disappeared once I saved the file to One Drive. Could it have something to do with saving to a cloud?
(p.s. I have version 21.001.20145 of Acrobat Pro)
Commenting here to see if anyone has a solution. This is so frustrating! My entire meeting's worth of notes are gone!! 😞
I just had the same issue. did you find an answer?
