Also I see you are making a common mistake, replying to someone on your control panel vs in the conversation with that person.
For example I sent you a message asking if you wanted to sahre battle record info with BABA and you replied on your control panel rather than clicking on veiw conversation and posting your response in our conversation thread. So I had no idea you had responded to me. Sme with Saving Grace. If you click on view conversation on post on it, your response will show up as a Visitor message on their control panel and they will get a new VM notification.
I still forget LOL
