Today I purchased several items and when I try to leave a review for any of them, I get the message: "You must purchase the product before you can review it." I tried logging out of MP and closing my browser. But when I log in and try again, I get the same message on every item. The only thing they have in common is that they were all gifts. However, the recipients of the gifts *also* cannot write reviews because they didn't make the purchase. When I try to review the one item I bought for myself, I am able to. So is this how MP is designed? Is there no way for buyer or recipient to review items that are gifts? Thanks!
