My friends and beta readers told me they made comments on the snapshot I shared with them. Where do I go to see those comments?
From within your project, navigate to the Project > Snapshots dialog. From here you can see all the snapshots for this project. Whether you created them from the "share" dialog or whether you created them from this dialog, they all show up in the Existing Snapshots section of this dialog.
For each snapshot, you see a column with the number of notes on that snapshot. That column represents the number of Suggested Edits and Comments that were made to your snapshot.
Click on "view" and you will be taken to the reading screen where you can see the comments people have made.
