I finally figured out how to get this to work. I don't seem to be able to edit the PDF Formatting. I edit the settings for row width, font size, etc. When I click on the link to download the file, the formatting changes I just saved do not appear.
Is this a caching issue? Or do I need to delete the link and start over with the new format?
Usually, to work with PDF format, I used several different tools from different resources and I can tell you that this is extremely inconvenient. But recently I discovered a very cool site https://www.pdfplatform.com/ where all the necessary tools and even more are collected. With this site, you can even sign your PDF documents with an electronic signature. Enjoy and don't thank me!
