The review process on Bunz requires commitment from both parties. The order of events is as follows:
Jordan sends Jana a review request by tapping the Request a review option in chat with Jana
Jana accepts the review request in chat once they receive the message
Jana and Jordan can now leave each other reviews
Jana and Jordan meetup for a trade
Jana reviews Jordan
Jordan reviews Jana
Note: Reviews are only enabled after a review request has been sent and accepted. Reviews are also visible immediately after they have been made. Individual Bunz also do not have the ability to edit or remove a review, so double check before you smash that review button!
