Hi, I wonder if you can help me.
I've recently created a plugin that is listening to the filter:messaging.notify hook, the plugin works correctly, however for some reason when people are messaging each other, the messages will not show unless you close the message and re-open it.
If the plugin is deactivated, messages instantly show.
I see that plugins used to make use of a callback, but I've looked at the code that that hook fires and it doesn't appear to need a callback.
I did try adding the callback for testing and it says that callback is not a function.
Am I missing a call or a hook I need to fire to make NodeBB complete the process of sending the message to the open message window?
