Remove duplicate comments in PDF
I have been given a PDF with a few hundred comments. When I open it however, the comments seem to create a set of duplicates. The duplicated set cannot be checked or deleted or otherwise edited, making tracking what has been done problematic.
I did some searching on the forums and found this script:
https://www.try67.com/tool/acrobat-reader-dc-remove-duplicate-comments
It reports an error when installed and acrobat is opened (GeneralError: Operation failed. App.addToolButton:9:Folder-Level:User:RemoveDuplicateComments.js The name for the toolbutton must be unique)
I've emailed the author for help but in the meantime, if anyone knows of any other method for removing duplicate comments, or knows what causes them, I'd be grateful to hear about it.
I suspect the PDF (mine originally) was commented by the proofreader using something other than acrobat (I have no way to check easily, proofreading was done elsewhere in a long project chain) and the commenter is identified only as "Windows" where I'd expect to see a name (not terribly useful), but either way I have to work from this!
I'm using all the latest Adobe CC versions of everything on MacOS Big Sur (Mac Mini M1).
