Some issues with editing documents

When I chatted with support
When I chatted with support, I had had two different people who took the files I had been trying to merge unsuccessfully and merge them for me!!! Similarly when I had trouble with blank pages and missing pages in a merged document I found out it was because I was using Edge as my browser instead of Chrome. It would have been best if that had been in the program itself, but support really came through to help me out.
Making signing easy
It was a great team friendly program that made things get done a lot faster and more efficiently even in large with large numbers working on the same thing.
Makes getting multiple groups of people working on one thing done faster with not all having to come to the same place.
Sometimes it was difficult trying to download the papers once the words were added.
