In order to see the feedback you received from the peer review activity, the peer review activity should be connected to a reflection activity. All reflection activities can be recognised from this little icon:

To view your feedback, go to the reflection activity. When you have received peer feedback, a blue button on this page will say 'reflect now'. Once you click this button a new page will open up with your feedback on the left, and a feedback reflection rubric on the right.

It could also be the case that there is no reflection rubric, that means that your instructor turned the reflection rubric off, and you can simply mark your feedback as complete to complete your reflection activity.
