Shamim, thanks for the response. No issue with message delivery. About the reported issue, this is the analogy:
When I typed a message and clicked on “Reply”, the url had to reload before message could be delivered. Just as if I placed the cursor in the url address bar and pressed enter on the keyboard. I expected the message to be delivered without url reload.
For example, when you are sending messages on facebook, message is delivered instantly without url reload.
