Liking it so far. But when I'm using the eraser, line, or other tool, it automatically changes back to text add mode after saving the change I've made rather than staying with the eraser, line drawer, etc. If you did it this way b/c more users keep erasing, adding lines, highlights, etc when they intend to make only one change and start typing then nevermind. I would rather it stay with the eraser, highlighter, etc. and I'll switch back to adding text when I'm ready to do so. Hope that helps.

I had issues at first as connections failed and I lost my documents that I had updated which took me a long time to do. I have had another go and it has worked a lot better.

At first I had difficulty understanding how to use PDF Filler maybe because the way the dashboard was set up was that there were too many icons that made it seem too overwhelming.
