Having used other proofing products in the past to run my magazine, I can say that this product is very good. Setting up an upload link was super easy. Acting as a client who is not logged in, I was able to upload a PDF easily. The app will upload the whole PDF and also split it into individual pages. I didn't want the individual pages uploaded, so I selected the ones for deletion. Well, I could not find the delete button and the delete key did not work. I asked Sophie for help, and she said delete was on the bottom corner of the file with the three dots. But that did not answer my question and I guess she thought I was an idiot. I finally figured out that bulk delete was in the upper right as three dots and explained to her that it was not intuitive for a client if they don't see a trash can. They will just select and upload thinking that they only uploaded the file they selected because that's what I did when I couldn't delete what I selected. What was Sophie's response? CRICKETS. I guess I've been spoiled by Flywheel's (WP Engine) Happiness Engineers. Having a bad day? I don't know, but don't forget customer service.
