When a piece of feedback is marked as resolved, it disappears from the My Dashboard/My Feedback view. This means that Process Owners/Experts need to remember which process the feedback was against to go looking for previously resolved feedback. Suggest adding a toggle to the My Feedback view to see all feedback, including resolved feedback.
This isn't on our near term roadmap but we'll monitor interest on this issue.
Currently, users have to remember which process they raised feedback against to view feedback that has been resolved or responded to but not resolved.
