Can I decide if all reviewers may see all scores and feedback?

When adding a Review, you many set the Lock and Score Privacy to Manual.

Click Add Review in the upper right corner.

For Lock and Score Privacy, select 'Manual'.

When the Lock and Score is set to Manual in creating the Review, the Score Privacy is set to Private till it is unlocked by the Review organizer.

Only the Review Organizer and those with Admin access will see the scores and feedback.

When Shared, all scores and feedback are shared with all invited to the meeting (and those with Admin access).

If the Lock and Score Privacy setting is set to Review Date, all review scores and feedback will be automatically shared with all participants on the review date.
