Not all users see checked comment checkboxes
Our team of authors use the comments checkboxes in Acrobat Pro DC to mark a comment as completed. This has been a mainstay of our review procedure for a while now but all of a sudden we can't use the feature any more.
I can see the checked checkboxes that I make myself, but when I look at another person's work, all of the checkboxes are blank, no matter that they checked them themselves. This means that we are suddenly actioning comments twice or more, and being confused as to what has and has not been done.
One user cannot even see empty comment checkboxes in other authors' pdf outputs, even though the 'Show checkbox in comment note' option is switched on.
How can we fix this please, it is an integral part of our review process and I don't want to have to rework our process if at all possible.
