Occasionally, when a reviewer opens an otherwise-healthy shared review, Acrobat forces that reviewer to take ownership of everyone else's comments. The consequences are:

• From Acrobat's perspective, the review now has only one active reviewer.
• Every comment starts with "On behalf of [original reviewer]".

So, for example, if a review had comments from Olivia, Shilpa, and Franklin, and the problem occurred when I joined the review, the review would now only have comments from me, and the comment text would start with "On behalf of Olivia", "On behalf of Shilpa", and "On behalf of Franklin".

This is undesirable because no one can filter by reviewer after the problem occurs. It also clutters the comment text itself.

Unfortunately the problem occurs highly intermittently, with no obvious root cause.

See https://community.adobe.com/t5/acrobat-discussions/reviews-and-prevent-to-take-ownership-of-comments/m-p/11208978 and https://community.adobe.com/t5/acrobat-discussions/shared-review-quot-on-behalf-of-quot-problem/td-p/11216621 for previous Adobe-community reports of this problem.

It is also possible that the problem occurs with Adobe Reader. Due to the intermittency of the problem, it's proven impossible for me as an end user to determine this.

Please fix this, so that shared reviews never attribute existing comments to anyone but the originator. Thanks.
