The UI is outstanding and very effortless. Very impressed. My only issue was with advanced features. Would have liked to know ahead of time that they were additional fee. Everything looks included and don't like being told something cost money after the fact. Second, when telling me I had to upgrade to get additional feature, it should show the difference between what I am paying verses the new amount. I was on personal plan ($6) but to get the features I needed it was ($10). It said it was $10 for advanced plan but I didn't know if that meant $10 MORE than I was already paying. I had to open site in incognito mode, look at plans to figure it out... not fun. Lastly, I was trying to send 2 separate PDFs as one doc. It took me a while to figure out where Merge was. I didn't understand why all the options under Actions were greyed out. That was very frustrating and should be improved.

I just wanted to fill one document but I don't have full adobe on this machine. Then I wanted to print and I had to buy it to print which was okay as I need a system. It works great now that I am learning how it flows.

It has been pretty intuitive. Had some issues with a long 70+ page doc at about page 50 it was going blank. Help chat sorted me out telling me how to delete cache which sorted this.
