Sorry Suzanne, We had a bug :-/
When courses did not require the Reviewers to log in then in some circumstances they would not be able to see or add replies. We pushed a fix for it today.
Great news! Thanks for letting me know! We will test this on our next round of reviews (hopefully next week.)
Some of our reviewers are able to reply to other reviewers' comments and other reviewers are not.
When uploading the course, I did check the box indicating that reviewers could see each others' comments. I also indicated that they did not need to log in as a requirement to review (in an attempt to make the process easier for them.)
We tried to make everyone a developer on the site so they could use the developer screens to have the discussions about a specific slide within the tool as a workaround, but this didn't work either. I believe we are limited to 5 developers on the site and we have about 8-10 people total on the project who need to be a part of the discussions.
How can we make it consistent so that all reviewers can see and reply to each others' comments? Does this require each reviewer has created a profile on the site and/or they all use the same browser? We are encouraging the use of Chrome, although that doesn't seem to solve the problem either.
