Hi! You've posted your question in the Canvas LMS Question Forum, part of the global Instructure Community. You can meet people using Instructure products and find official support guides here. However, because of the individual settings your instructor applies to each of your assignments, we are unable to provide the reason why you are unable to complete your peer review.
Please reach out to your instructor directly and ask for confirmation about the availability dates of the activity. How do I use the Inbox as a student?
