I am running 3.4 and finally got annotate PDF to work. However, it is adding a blank page to the start of every submitted document, does not matter if it is docx, rtf, pdf. So a 5 page submission becomes 6 pages with a blank first page.
I searched and found MDL-59772 which referenced this issue in Moodle 3.2. Status is incomplete and closed. Do we think this was corrected in Moodle 3.4 or are others out there experiencing this problem?
Of note is that we do not use unoconv; we use the Google text converter with ghostscript.
