Can't leave feedback from the conversation page. I click on "add feedback" and fill out all fields, including selections: trade type (seller) and feedback (positive). But I get this error ( see attached). Also, there's no option to get back and correct feedback, so everything I typed gets lost and I have to try again from scratch! This is not good taking into account that I have severe tendonitis and every additional typing hurts me more and more. Will appreciate your fix
