Is there any way for me to try it actually works before buying the premium license?
Given this thread from 2014: http://www.phpdocx.com/en/forum/default/topic/823 it says the trial version doesn't include this feature.
I tried both: creating a new file, and creating from template, none of them added/modified a document properety (but the watermark and trial version parragraph were added).
I want to make sure this actually works before letting my boss know it works so we can buy this library license.
