Per CS0025733, we have been told that when a new version is uploaded to a task, previous Reviewer Comments are not retained. Only Reviewer Comments from single versions made throughout are retained until a new version is uploaded, then the Reviewer Comments start anew. This is not how our reviewers would like to see this work. They need the ability/insight to see all previous Review Comments throughout the Activity.
Aprimo Customer Support comments to ticket CS0025733: "We would not retain the review comments from the first version once it's been replaced by the 2nd. We assume that the comments in Version 2 are now the comments that are important since Version 1's comments should have already been addressed. This is Functioning as Designed."
