Our team is struggling with comments going unseen in the proofing process. Many of our reviewers only use wrike occasionally, so it's been difficult to get them to adopt the nuances of all the at mentioning needed to get someone's attention.
Reviewer A makes some comments and marks the proof approved.
Reviewer B later comes in and responds to Reviewer A's comment with a follow-up question but doesn't @ mention Reviewer A, they do not mark the review status because they want their question answered first.
Reviewer A will never see this question until the project manager or designer goes in to see what the hold-up is, reads through the exchange, and possibly has to contact Reviewer B to see why they haven't marked a review status.
The software could alert reviewers when someone responds to their comment; send them an alert that they need to re-review or somehow give them a task and an email with a link to what they need to address/respond to. Or if someone is responding to comment perhaps the system could flag it before hitting enter with a tooltip: you haven't @ mentioned anyone, make sure to @ mention anyone you want to read this comment..
Our old proofing tool offered some kind of alert, which allowed for more discussions to happen between reviewers and it saved a lot of leg work for the PM/designers because the reviewers were able to discuss and deliver answers all within the proof.
