The option to review isn’t showing up on all products. The tab shows up, but not the ratings/comment box, etc.
I've set it to allow reviews in WooCommerce as well. Maybe you can help me out here? Not sure why they aren't showing up.
Also, maybe for a future release… one thing to note is that for the seller it shows the option to View/Comment on reviews, but they basically get the same review box and if you have ratings required they would have to input stars to comment. I've temporarily disable the requirement for ratings, but it is still a little confusing.
