Chat notification: action:notification.pushed not triggered

[JJSagan]

Hi Devs,

I understand that chat notification occur when the target user is not directly focused on the chat itself. I further understand that the notification will also be delayed by about a minute just in case more messages come in.

However, in the latest version, it seems that when chat is sent, the target user will not get notified within 1 minute (pending the above). Actually, action:notification.pushed is triggered after few minutes, if at all.

Anything I am doing wrong?

Thanks!
JJ.
