Text field, watermark, arrow, and distance tools are not leaving comments in Docx files.
I figure out that some of them are not leaving comments just in black spaces, for example, arrow, distance, and text tools, but the watermark is not leaving comments never. I can see the comment in the web application, but not in the downloaded annotated file.
I had this problem on version 19.4, so I updated it to 19.7, as the bug is still in this version I’m updating my application to the newer version 21.7, but in the meantime, I made a test on the live demo application and I saw the bug is still happening.
