I was messaging with someone and the message was deleted. I cannot tell if it was an accident or on purpose. A prospect was messaging me to meet up. The prospect asked for my email to schedule time. I replied that we could use the scheduling system within upwork and choose an available time I set up. Then all of the sudden the messages disappeared. Not sure if this was an accident or on purpose. Can I view/recover a message that was deleted (assuming this prospect was a real prospect)?
