Stamps & "fill & sign"
with Adobe Reader XI, we add a stamp to a pdf document (not a form) and apply initials using "fill & sign". The document is then be reviewed by a second person, who also adds a stamp and applies their initials. After each stamping/initialling action, the next person could not modify or delete the stamp, and we used this as a simple way of recording when documents were reviewed & approved for release (much more efficient than obtaining ink signatures and scanning documents).
With Reader DC, when we apply the stamps and initials, anyone can move or delete these stamps. I've read several posts on the forums that suggest that this should not be the case, that the stamped/initialled document is "flattened" when saved, but that is not what I am seeing.
I've tried several versions of DC over the past few months (most recently on 30th Dec 2017) hoping with each new version that the issue is resolved, but see the same behaviour each time.
Is ther a quick fix for this? Some setting that I'm missing? Please don't direct me to "cloud based services" as this is not a suitable option for our application.
