When power user shares a report with other users, it does not sync when users make changes to that report.
This is by design
This is only one way sync by design. When power user shares the report to other users, the shared reports becomes stand alone for end users. The only way to sync changes are when original person who shared the report makes changes to the report and clicks publish to push the changes to end users. When end users make changes to the shared report, the changes will not sync back as it is stand alone report for end users. It is only one way sync.
