Thanks for getting in touch. Hmm, this is not an issue that's a confirmed bug from our end, so I'd like to look into this in further depth for you. I've set this convo right here to private in order to investigate with the necessary information.
Can you send over the user name and URL of the user to whom you sent a message and who claimed to have responded to you? This way I can look into the details for this.
