Captivate Reviewer - correct setup for communal comments

G'day,

I'm trying to set up Captivate Reviewer (v2019) for the first time and I'm following the instructions correctly, as far as I can tell, but when I open the .crev file (that I put on our local Windows server volume) I'm getting the following warning message:

"The comment store location is a local directory. Export comments to author to complete the review."

When I did the initial "Send for Shared Review" setup, I chose the same network drive for the "Publish Folder" as well as the "Projects comment folder" so the comments are definitely not sitting locally.

What am I missing???

Thanks!!!

Brett
