This product uses the same support system as Roboform, which is also one of their products.
I was able to set up a job connecting a folder to Dropbox, but when I went to set up a second job with a different local folder connecting to Dropbox, I got all sorts of errors and issues.
I recognized the support immediately because I posted the issue on the support site in painstaking detail, and the response was “Please describe your issue in detail”.
It seems to be all cut-n-paste stock boilerplate phrases that don’t address the issue, which is precisely how Roboform support works. After a few back and forths (to come) I expect the same dismissive attitude implying I’m an idiot for having the problem, precisely the way it works in Roboform.
FYI
So while I’m still not totally thrilled with the support page, I am an idiot, and this one was my fault. I found the problem, fixed it, and posted that it was my fault and closed the ticket.
This is one of the very few solutions for copying/syncing to the Dropbox cloud without having to have the files on your local machine be in or under the Dropbox folder, and as such, it works quite well.
